#WPNinjasNL Saturday 2026

Culemborg, 🇳🇱 Netherlands

Details
The Workplace Ninja User Group Netherlands is proud to announce that on Saturday the 7th of November 2026 we will organize our WPNinjasNL Saturday in-person event 2026.

Program:
10:00 - 16:00: Welcome at location, workshop by the Workplace Ninja User Group Netherlands Team, with special Guest Rudy Ooms

WPNinjasNL Saturday – Microsoft Intune: Learn. Build. Break. Fix.

Een hele dag luisteren naar presentaties? Dat gaan we dus niet doen.
Tijdens deze WPNinjasNL Saturday draait alles om leren door te doen. In deze intensieve, hands-on masterclass combineren we korte technische deep dives met praktische opdrachten waarin je de besproken technieken direct zelf gaat configureren, testen en verbeteren.
En voor deze speciale zaterdag hebben we Rudy Ooms uitgenodigd.
Wie Rudy kent, weet wat dat betekent: we blijven niet hangen aan de oppervlakte. We kunnen écht de diepte in, kijken wat er onder de motorkap gebeurt, onderzoeken waarom bepaalde dingen zich gedragen zoals ze doen en waar nodig technische grenzen opzoeken.
Dus verwacht geen dag vol “klik hier, klik daar”, maar een technische deep dive waarin we theorie, praktijk, troubleshooting en internals met elkaar combineren.

Het principe gedurende de dag is eenvoudig:
Learn → Build → Test → Fix

Onze experts introduceren een onderwerp in ongeveer 10 tot 15 minuten, laten zien waarom het belangrijk is en demonstreren hoe het werkt. Daarna ga je zelf aan de slag in een labomgeving. Geen presentatie van 60 minuten, maar precies genoeg theorie om te begrijpen wat je gaat bouwen — en vooral waarom.

Van scenario naar oplossing

We behandelen onderwerpen niet als losse features, maar vanuit herkenbare praktijksituaties.
Op Identity-gebied kun je bijvoorbeeld denken aan:

  • Een Adversary-in-the-Middle-aanval waarbij we eerst laten zien wat er gebeurt en deelnemers daarna zelf maatregelen bouwen met phishing-resistant MFA, Authentication Strengths en Token Protection.
  • Misbruik van Device Code Flow, waarna je zelf Conditional Access-maatregelen ontwerpt om het risico te beperken.
  • Het beschermen van privileged accounts en het verschil tussen normale gebruikers en administrators.
  • Het combineren van Conditional Access, device compliance en identity-signalen binnen een Zero Trust-aanpak.

Op het gebied van Device Management gaan we net zo praktisch te werk. Denk bijvoorbeeld aan:

  • Een Intune-policy die niet aankomt op een device. Waar gaat het mis: assignment, filter, applicability, client-side processing of iets anders?
  • Configuration drift: een instelling wijkt af van de gewenste configuratie en je moet deze detecteren en automatisch herstellen.
  • Een Win32-applicatie die niet installeert, waarbij je aan de slag gaat met detection rules, requirements, dependencies en de Intune Management Extension logs.
  • Een mislukte Autopilot-deployment waarbij je onderzoekt waar het proces stokt en hoe je dit structureel oplost.
  • Complianceproblemen waarbij je onderzoekt wat het device rapporteert, hoe Intune dat verwerkt en wat uiteindelijk de impact is op Conditional Access.

Juist in die scenario’s kunnen we met Rudy nog een extra technische laag toevoegen: wat gebeurt er daadwerkelijk op de client, welke logs zijn relevant, welke processen spelen op de achtergrond en hoe troubleshoot je wanneer de portal je niet direct het antwoord geeft?

Geen vaste demo’s, maar echte techniek

De exacte scenario’s kunnen gedurende de dag worden aangepast aan nieuwe ontwikkelingen en aan de groep.
WPNinjasNL Saturday gaat namelijk niet alleen over hoe iets volgens de documentatie zou moeten werken, maar vooral over hoe het in de echte wereld werkt.
Daarbij zoeken we bewust de verbinding tussen Identity en Device Management. Want een moderne werkplek stopt niet bij Intune en security stopt niet bij Entra ID. Juist de combinatie bepaalt uiteindelijk hoe veilig, beheersbaar en gebruiksvriendelijk je omgeving is.

Bring Your Issues

Heb je een Intune-, Entra- of endpoint-managementvraag waar je al een tijdje tegenaan loopt?
Neem hem mee.
Bij je inschrijving kun je vooraf jouw technische uitdaging, vraagstuk of probleem insturen. Vooraf selecteren we een aantal interessante cases voor onze Bring Your Issues-sessie.
Tijdens de dag pakken onze experts deze vraagstukken live op. We analyseren het probleem, onderzoeken mogelijke oorzaken en proberen waar mogelijk samen tot een werkende oplossing te komen.
Juist met de combinatie van verschillende expertisegebieden — waaronder de diepgaande technische kennis van Rudy Ooms — kunnen we hierbij verder gaan dan alleen de portal en ook kijken naar wat er daadwerkelijk op het device en in de achterliggende componenten gebeurt.
Geen vooraf opgenomen demo en geen perfect voorbereid scenario, maar echte problemen uit echte omgevingen.

Voor wie?

Deze dag is bedoeld voor IT-professionals die al met Microsoft Intune en Microsoft Entra werken en verder willen dan alleen weten waar een instelling in het admin center staat.
Denk aan:

  • Microsoft Intune administrators
  • Modern Workplace engineers
  • Endpoint management consultants
  • Identity- en security engineers
  • Microsoft 365- en Entra-specialisten
  • Architects die moderne endpoint- en identity-oplossingen ontwerpen

Basiskennis van Microsoft Intune, Microsoft Entra ID en Conditional Access is aan te raden.

Wat neem je mee naar huis?

Aan het einde van de dag heb je niet alleen nieuwe mogelijkheden gezien, maar ze ook daadwerkelijk zelf gebouwd en getest.
Je hebt beter inzicht in hoe Identity en Device Management op elkaar ingrijpen, welke ontwerpkeuzes je in de praktijk tegenkomt en hoe je problemen structureel kunt analyseren en oplossen.
En minstens zo belangrijk: je begrijpt beter waarom iets werkt — of soms juist niet werkt.
En natuurlijk sluiten we WPNinjasNL Saturday af zoals het hoort: met een borrel, technische discussies en genoeg gelegenheid om ervaringen uit te wisselen met andere Workplace Ninjas.

Discussion group - The PHP incident

Utrecht, 🇳🇱 Netherlands

When AI finds the bug first: who governs the window?

On 21 October 2026, PHP, the programming language behind roughly 70% of websites, released emergency fixes for two critical flaws, together called PHP2Shell. Researchers found them with frontier AI models, including OpenAI's GPT-5.6 Sol and Google's Gemini 4 Argon. In the Netherlands, the NCSC, DigiD, MijnOverheid, the Tweede Kamer and parts of the higher-education network went offline as a precaution. OpenAI presents the case as AI finding the flaws before attackers did, and has proposed a five-stage process for coordinating such disclosures, with governments brought in along the way. Yet the embargo broke early, exploit attempts appeared days before disclosure, and the researcher who found the first flaw says he used publicly available models. This week we ask who should govern the window between an AI finding a flaw and the world patching it. We pair the news with a June 2026 expert consultation by the US National Academies, which expects AI to favour attackers in the near term and finds that defensive work such as patch deployment is the hardest part to speed up.

Questions we'll explore

  • Did AI help defenders or attackers more in the PHP incident? How would we know?
  • Should a private AI lab coordinate a global security response and decide who hears first? If not, who should?
  • Were the Dutch precautionary shutdowns, from DigiD to the Tweede Kamer website, proportionate?
  • Should access to the most capable cyber models be restricted, and who should decide who gets it?
  • The National Academies find that patch deployment is the hardest part of defence to speed up. What would help the Netherlands patch faster?

Format (90 min): Discussion in small groups and plenary. No presentations, no wrong questions.

Readings:

How to prepare: This is a standalone session; no lecture needed. Please reserve about 1.5 hours, ideally over a few evenings. Short on time? The ★ items (about 1 hour) are the essentials.

Part 1 (~35 min): what happened

  • ★ ~10 min: AP, Websites scramble to fix software flaw that could put much of internet at risk
  • ★ ~5 min: NL Times, Some important Dutch websites still offline after PHP issues
  • ~10 min: BCS, Analysis: the global PHP incident, the view of the UK professional body for IT
  • ~10 min: AI Weekly, PHP2Shell roundup, on the credit dispute, the broken embargo and early exploitation

Part 2 (~35 min): the academic lens

  • ★ ~15 min: OpenAI, Coordinated disclosure of critical vulnerabilities, the five-stage process. No time? Read the PPC Land summary instead.
  • ★ ~20 min: National Academies of Sciences, Engineering, and Medicine (2026), Implications of AI for Cybersecurity: A Rapid Expert Consultation. Read the chapter Artificial Intelligence and the Changing Cybersecurity Landscape (pp. 4–7).
  • Optional: Shevlane & Dafoe (2020), The Offense-Defense Balance of Scientific Knowledge: Does Publishing AI Research Reduce Misuse?, AAAI/ACM Conference on AI, Ethics, and Society (~30 min). On when disclosure helps defenders more than attackers.

Part 3 (~15 min): reflection

  • ★ ~15 min: note whether you think AI helped defenders or attackers more in this case, one stage of OpenAI's five-stage process you would rather give to a public body than a company, and one finding from the National Academies that the PHP incident confirms or contradicts

November 2026: Kotlin-Powered Spring Boot and the Security of LLMs

Groningen, 🇳🇱 Netherlands

Join us on Tuesday, November 10th for another engaging JUG Noord meetup in Groningen, where we’ll explore how Kotlin can take Spring Boot development to the next level and uncover the security risks, vulnerabilities, and challenges that come with integrating LLMs into modern applications.

📅 Date & Time:
Venue opens: 16:30
First talk starts: 17:00
Food & drinks: Provided between the sessions

📍 Location: Kempkensberg 12, Groningen

🚨 Important: Signing up and valid identification are mandatory for entry. If the name on your Meetup profile does not match your ID, please contact Martijn (organizer) with your full name.

🇬🇧 Things you can do with Spring Boot and Kotlin by Frederik Pietzko (JetBrains)
In this talk, I’ll show you how to build microservices efficiently using Kotlin and Spring Boot.

We’ll begin by exploring Kotlin as a drop-in replacement for Java and gradually dive into Kotlin-specific features and libraries that significantly enhance development. We’ll also take a closer look at Kotlin DSLs for Spring Beans, Routing and Security as a sleek alternative to annotation-based configurations, essentially turning Spring Boot into a microframework.

Come and join me on this live coding adventure!

You will leave knowing how to turn any "could I automate this?" moment into a working optimization solution.

🇬🇧 The S in LLM stands for Security by Ties van de Ven (Alliander)
LLMs are all the rage these days and are increasingly being added to more and more products. At the same time we see companies using GenAI to assist or even replace software engineers. But as with any new technology this also brings risks that we need to be aware of in order to use it properly. Since GenAI is still an evolving field, new attacks and vulnerabilities are regularly discovered.

Join this session in which Ties van de Ven explores the most common use cases for LLMs (code assistance/agentic flow, applications built around LLMs, MCP, and model selection) and discusses possible attacks, exploits and mitigations.

About the speakers
Frederik is a Developer Advocate at JetBrains, passionate about building the best possible products, and regularly presents at international conferences and writes the occasional blog post.

In his free time, he likes to explore programming languages and frameworks, meet and chat with other software enthusiasts, and play with his cats.

Ties is a software engineer with passion for concepts, sofware engineering fundamentals and helping others. He combines these passions by doing public speaking, volenteer work for organisations like Devoxx4kids and codingcoach and working as a Software Quality Expert at Alliander.

AI AT WORK Amsterdam - Trust, Risk & the EU AI Act

Amsterdam, 🇳🇱 Netherlands

Who is accountable when an autonomous agent makes the call?

Part of AI at Work, a series hosted by Isabel Shestopal and Epicenter.

When an AI agent places an order, approves a refund or acts on customer data, who is responsible? The coworker using it, the company deploying it or the provider behind it? And what role should government play in setting the rules?

In this edition of AI at Work, we’ll explore what the EU AI Act means for businesses and the people working in them. What should employees check before trusting an AI decision? What must companies put in place, and who steps in when something goes wrong?

We’ll also discuss the business case for safe AI. Can companies earn customer confidence and win business by showing that their AI is secure, reliable and under control? What does that take in practice, and what does it cost?

Finally, we’ll explore AI sovereignty: where companies build and run their AI, who can access their data and what happens if a provider changes its terms or becomes unavailable. How much dependence is a business comfortable with?

Join us for a practical conversation about using AI responsibly, sharing accountability and knowing when to keep a human in charge.

Panel

  • Sohrab Hosseini, Co-Founder / CEO @ Orq.ai
  • **Alexander Galt, **Digital Ethics Leader @IKEA & Board member at MyData
  • Joseph Bianchi, Consulting founders on ai, org ops, & structural risk

Building AIOps with an Ironman Mindset by Nikhil Gupta

The Ironman triathlon is about endurance, disciplined preparation and controlled transitions. Flow and reliability are no different.
When an incident starts, responders need to understand customer impact, identify affected dependencies and decide what is safe to do next. But the evidence they need is often scattered across dashboards, deployment records, service catalogs, runbooks and other knowledge sources. Under pressure, responders have to reconstruct that operational context.
In this talk, Nikhil Gupta explores an AIOps design that continuously prepares this context and makes it available when it's needed.
Using a payment-service incident as an example, he'll explore investigations triggered by confirmed customer impact versus those triggered by an earlier anomaly. We'll see how an AI agent can choose read-only tools, collect evidence and propose verification steps while keeping the human responder responsible for operational decisions.

What you'll take away

  • How to identify context gaps that force responders to reconnect evidence manually during incidents
  • How to separate deterministic context preparation from probabilistic AI reasoning and human decisions
  • How to bound agent investigations using read-only access, tool-call budgets, stop conditions and evidence trails
  • Ways to evaluate AI-assisted investigations using diagnosis accuracy, responder rejection, time to first validated fact and lead time before confirmed impact

About Nikhil Gupta
Nikhil is a Product & Engineering Leader with passion for AI and Platform Engineering and is based in Amsterdam. Nikhil has experienced first hand how Platform Engineering and DevOps transformations play out in organizations of very different scale, from 20+ teams to 2000+ teams. Nikhil is leading the AIOps and Observability Engineering teams at ING. Nikhil like to write about Leadership, Platform Engineering, Observability and AI.

🤖 23 Ways to Use an AI Agent in a Platform Engineering Team at RTL NL by Anna Kosek and Myroslava Tarcha

At RTL Netherlands, the team built Thanos, an AI agent that started life as a Slack chatbot and evolved into a platform engineering agent with more than 20 capabilities.

It reviews pull requests on Azure DevOps and GitHub, queries Grafana using natural language, generates architecture diagrams, manages work items and release notes, analyses build failures and supports automated incident root-cause analysis.

But the most interesting lesson isn't simply what the AI can do.
It's the human-in-the-loop patterns, identity-aware operations and trust model that made engineers actually want to use it.

In this fast-paced session, Anna Kosek will take us through 23 real-world use cases, complete with practical examples, honest failures and patterns you can take back to your own engineering teams.
No infinity stones required. Just a Kubernetes cluster and an open mind. 😉

🏗️ 7 Ways to Fail at Building a Platform by
Michael Coté

Building your own internal developer platform can look attractive. But when you build it, you also own it. Suddenly, you're in the business of developing and maintaining a product alongside your actual business.

Drawing on 10 years of platform engineering case studies from large organizations, Michael Coté will walk us through seven common risks of building your own platform:

Expansive scopes. Underestimating cost. Project mindsets. Death by customization. Skills. Security and compliance. Resume-driven development.

More importantly, he'll look at what organizations can do differently, including:

  • Discovering the full scope of platform engineering across organizational silos
  • Calculating costs and performance end-to-end
  • Evaluating build-versus-buy decisions for internal developer platforms
  • Creating a platform engineering strategy and staffing plan
  • Applying product management thinking to platform engineering

Learn from organizations that have already encountered these problems so, hopefully, you don't have to repeat them yourself.

About Michael Coté
Michael Coté studies how large organizations improve the way they build software to run and grow their businesses. He's been an industry analyst at RedMonk and 451 Research, worked in corporate strategy and M&A, and was previously a programmer.
He's also the author of Changing Mindsets, Monolithic Transformation and The Business Bottleneck, and co-hosts podcasts including Software Defined Talk and Software Defined Interviews.

Utrecht JUG Meetup – Nov 11: Java Security & Agentic AI in Legacy Modernization

Nieuwegein, 🇳🇱 Netherlands

We’re excited to welcome you to Utrecht JUG on November 11th, hosted by PSG Technauts. Join us for an evening full of Java, AI, software architecture, practical insights, great conversations, food, drinks, and plenty of opportunities to connect with fellow developers.

We’ll start the evening with food and drinks before diving into our first session, where Ana Maria Mihalceanu, Java Champion Alumni and Certified Architect, explores the future of Java security in the age of quantum computing. From Hybrid Public Key Encryption (HPKE) to post-quantum hybrid key exchange in TLS 1.3, Ana will demonstrate how Java developers can prepare their applications for emerging security challenges, using keytool to manage keys and certificates and JDK Flight Recorder (JFR) to inspect security details at runtime.

After the break, Marek Dominiak, CTO, architect, tech lead, and IT trainer, takes us behind the scenes of modernizing a Java monolith with more than two million lines of code using agentic AI. What happens when AI agents help rewrite a critical legacy feature, the initial checks look promising, but the first production release fails? Marek shares what went wrong, how the team recovered, and how the lessons learned led to a third version that finally worked in production. He’ll explore where AI agents saved time, where they went off track, and how disciplined engineering practices made the difference between a failed release and a successful modernization.

Whether you’re interested in the future of Java security or the practical realities of using agentic AI to modernize legacy systems, this meetup offers plenty of insights to take back to your own projects.

Please join us and RSVP!

Because of the limited number of seats, please keep your RSVP up-to-date, so we can welcome someone else if you can't make it.

20:00 Modernizing a 2M+ LOC Java Monolith with Agentic AI: What Worked, What Failed, and How We Recovered — Marek Dominiak
21:00 Drinks


Talks Securing Java for the Quantum Era

Most Java applications rely on cryptography every day, often without much thought, because we trust the algorithms underneath. But as computational power advances, how much of that trust will hold up?
The risks aren't far off. Encrypted data captured today could be decrypted years from now, putting greater pressure on how we secure applications today.

In this session, we'll explore modern Java security, from the concepts behind Hybrid Public Key Encryption (HPKE) to a hands-on demo of post-quantum hybrid key exchange in TLS 1.3, using keytool to manage keys and certificates and JDK Flight Recorder (JFR) to inspect security details at runtime

Modernizing a 2M+ LOC Java Monolith with Agentic AI: What Worked, What Failed, and How We Recovered

Modernizing a 2M+ line Java monolith meant much more than upgrading Java, Spring, Hibernate, and Elasticsearch. We also had to deal with tightly coupled dependencies, abandoned libraries, outdated patterns, and features that had been too risky to change for years.

This talk focuses on one of them: a critical indexing feature that needed to be rewritten to improve performance, fairness, and maintainability.
I'll show how we used agentic AI to analyse the legacy implementation, divide the work into manageable loops, and build a new version. It looked promising and passed our initial checks, but the first production release failed.

I'll explain what went wrong, how we recovered, and how the lessons from versions one and two led to a third version that finally worked in production.

You'll also see the engineering safeguards that made this possible: controlled context, clear instructions, automated tests, review, monitoring, rollback, security checks, and an explicit definition of done.

This is not a story about AI magically fixing legacy code. It is a practical case study about where agents saved time, where they drifted, and how disciplined engineering turned a failed release into a successful modernization.


Speakers Ana Maria Mihalceanu

Ana is a Java Champion Alumni and Senior Developer Advocate for the Java Platform Group at Oracle, with an extensive background in Java and cloud development. More recently, her work has expanded to explore how machine learning and AI can be applied within the Java ecosystem, helping Java developers adopt emerging capabilities while continuing to benefit from the stability, tooling, and performance of the Java Platform. She actively supports the growth of technical communities through knowledge sharing and enjoys curating content for conferences as a program committee member.

I’ve spent a lot of time mentoring developers and leading teams, with a big focus on creating solutions that will actually last for many years. That got me into Software Craftsmanship, Domain-Driven Design, and code quality early on.

Over my career, I’ve completed many small and large projects that run in production, interviewed developers, handled communication with customers, designed architecture for entire systems and delivered them, and introduced many technologies proven in production. I have 15 years of experience working in the Scandinavian market.

Pie & AI The Hague: New Jobs in the Era of AI

The Hague, 🇳🇱 Netherlands

AI is not only changing existing jobs - it is also creating entirely new ones.
As organizations begin to adopt AI at scale, new roles are emerging at the intersection of technology, business, security, law, governance, and organizational change. But what do these jobs actually involve? What skills do they require? And why are organizations starting to need them?
On Thursday, 12 November, join us at the main location of The Hague University of Applied Sciences for a new edition of Pie & AI, where we will explore three emerging professions in the age of AI:

🗣️ AI Translator
🔐 AI Security Engineer
⚖️ AI Governance Specialist

Rather than speculating about what future jobs might look like, we will hear directly from people already working in these emerging fields.

💡 Why attend?
AI is changing much more than the technical job market. Organizations increasingly need people who can translate between AI and business, secure AI systems, and ensure that AI is governed responsibly.
This event is for anyone interested in how careers are evolving alongside AI, whether you work in technology, business, law, cybersecurity, governance, education, or are simply curious about where the job market is heading.

As always with Pie & AI, there will also be plenty of opportunity to meet other people from the AI community, exchange ideas, and continue the conversation after the talks.

And of course, there will be pie! 🥧

🥧 Program
17:00 – 18:00: Walk-in and dinner with savory pies
18:00 – 18:25: Presentation 1
18:25 – 18:50: Presentation 2
18:50 – 19:15: Presentation 3
19:15 – 21:00: Drinks, discussion and networking

📍 Practical information
📅 Thursday, 12 November 2026
🕔 Starting at 17:00
📍 The Hague University of Applied Sciences - Johanna Westerdijkplein 75, 2521 EN, The Hague

Come for the pie, stay for the AI. 🥧🤖

🎤 Speakers & Talks

🗣️ Peter Becker - AI Translator
Peter Becker is lecturer at The Hague University of Applied Sciences, teaching in bachelor and master programs on data science & AI. He also provides in company training on AI and document management for governmental organizations.

Talk:
The Hague University has started a new master program: AI translator. What is an AI translator, why is it needed and what does a Translator do? Peter will talk about the challenges of AI implementations a translator faces.

🔐 Davide Cioccia - AI Security Engineer
Davide Cioccia is the founder of DCODX, an ethical hacking, and security training firm focusing offensive and AI security. Speaker and trainer at multiple international conferences like Black Hat, DEF CON, HITB, OWASP AppSec and NDC, he is currently leading the AI Security Engineer Netherlands chapter in Amsterdam.

Talk:
Everyone suddenly wants an AI Security Engineer, but nobody seems to agree on what that actually means. From breaking AI systems to securing agents, and from using AI to hunt vulnerabilities to redesigning Product Security itself, this talk explores AI for Security versus Securing AI and the strange mix of offensive, defensive, architecture, and AI skills behind this emerging role.

⚖️ Kanan Dhru - AI Governance Specialist
Kanan Dhru is a 3x legal innovation founder, investor, and academic working at the intersection of law, design, and technology. Kanan holds a law degree from the London School of Economics and a Masters in Public Administration. She currently serves as researcher at the Multilevel Regulation Lectorate in Legal Technology at The Hague University of Applied Sciences. Beyond academia, she consults in the legal AI space, advising leading law firms and government bodies. She serves as an Operational Board Member of Legal Hackers, as well as serve as the Advisor to the Global LegalTech Hub and TEDLaw. As an entrepreneur, she founded Lawtoons, an award-winning legal design initiative that uses comics to make law accessible to children.

Talk:
AI governance is becoming a profession of its own. Across public and private sectors, organisations need people who can turn principles and regulation into everyday practice. This can take shape of risk assessments, audits, policies and accountability structures. My presentation will look at the roles taking shape in this intersection of law, technology and ethics, and at what are the newer skills being called for.

Copilot Connect: From Rollout to Routine

Capelle aan den IJssel, 🇳🇱 Netherlands

Op donderdag 12 november organiseren we samen met Silverside een nieuwe editie van Copilot Connect: From Rollout to Routine.

Tijdens deze avond staat één onderwerp centraal: de adoptie van Copilot. Veel organisaties hebben Copilot uitgerold, maar dagelijks gebruik ontstaat niet vanzelf. Wat is er nodig om van een uitrol een gewoonte te maken, wat werkt in de praktijk en waar loopt het vast?

De avond bestaat uit twee delen. Je krijgt een praktische adoptie-aanpak die je direct kunt toepassen en je hoort van een organisatie hoe zij Copilot in de praktijk hebben laten landen, inclusief wat goed ging en wat ze anders zouden doen.

✨ Wat kun je verwachten?

  • Een praktische adoptie-aanpak: hoe maak je van een uitrol een gewoonte in het dagelijkse werk
  • Een klantverhaal uit de praktijk: wat werkte, waar liep het vast en wat leerden ze ervan
  • Interactie met andere Copilot-gebruikers, adoptieconsultants en beslissers

👥 Voor wie is dit evenement bedoeld?
Adoptieconsultants, changemanagers en Copilot-champions, business professionals en eindgebruikers, IT-consultants, Microsoft-partners en managers die willen dat Copilot een vast onderdeel van het werk wordt.

🎤 Sprekers

  • Roland Driesen is oprichter en strategisch consultant bij Silverside. Nico Scheppink is Senior Consultant bij Silverside en Product Owner van PACE. In hun sessie “Van Copilot-enthousiasme naar geborgde transitie” laten ze zien hoe je Copilot-adoptie praktisch organiseert via acht samenhangende routes in vier fases, van richting geven tot borgen in het dagelijks werk.
  • Remmie de Groot is Product Owner Hyperautomation bij Gemeente Zwolle. In haar sessie “Copilot Accelerate bij Gemeente Zwolle: van activatie naar borging” neemt ze je mee in hoe Zwolle ruim 400 medewerkers meenam in Copilot en hoe de organisatie nu met een netwerk van ambassadeurs werkt aan borging. Met een eerlijk verhaal over wat werkte en wat anders liep dan verwacht.

📍 Praktische informatie
📅 Datum: Donderdag 12 november
📍 Locatie: Silverside, Rotterdam
🍽️ Eten en drinken: Inbegrepen + een borrel om de avond af te sluiten
⏰ Tijdschema: 17.00 uur: Inloop | 17.30 uur: Diner | 18.00 uur: Start sessies | 20.30 uur: Borrel (mogelijkheid om vanaf 15.00 uur bij Silverside op kantoor te werken in verband met files, indien je hier gebruik van wilt maken stuur dan even een mailtje naar dani.brandsema@wortell.nl)

Scaling with Purpose: From Product Growth to Outcome-Led Leadership

Amsterdam, 🇳🇱 Netherlands

Hi Product People,
We are excited to invite you to our next event!
In this session, we will discuss how product leaders can grow products and organizations without losing focus, speed, or alignment. Through practical lessons on scaling teams and leading through outcomes, the talks will show how to turn strategy into meaningful impact—not just more features or faster delivery.

ABOUT THE TALKS

  • The growth playbook: what you need to scale your product, and your org

Speaker: Francesca Cortesi, CPO at Vend

Most product orgs know they need to scale, but they keep hitting the same walls: constant pivoting that kills momentum, teams that slow down instead of speed up, and innovation that feels like feature bloat.
Drawing from scaling some of the leading marketplaces in the Nordics, Francesca will share her hard-learned playbook: why focus beats flexibility when finding market-fit, how to structure for speed without chaos, and when to stop optimizing features and start rethinking the product.

Francesca is a product leader who has made impact, innovation, and sustainable growth the cornerstones of her career. With nearly two decades scaling technology-driven companies across the Nordics, she has led major marketplaces, online communities, and e-commerce businesses from early potential to scale.

  • Leading through Outcomes

Speaker: Alexandru Bleau, Senior Product Manager at E.ON

When nobody reports to you, the outcome is your authority. In this talk I'll show how leading through outcomes puts everyone on equal ground, turns a nod in planning into a real commitment, and gives you the most effective way to say no. And now that AI lets us build the wrong thing ten times faster, it matters more than ever.
Alexandru is a seasoned product leader, currently @E.ON One working as a Senior Product Manager. He has been building and developing products and services for 15 years, from advertising products, online services, and mobile apps to games, physical, educational, and travel products.

SCHEDULE

5:45 Arrive, grab a bite & drink

6:15 Welcome from ProductTank Amsterdam team and Funda
6:25 - 8:00 Talks and Q&A with speakers

Afterward, we’ll have plenty of time to mingle and talk product over drinks.

Location, Food & Drinks are sponsored by Funda. Thank you for supporting ProductTank Amsterdam!

Laravel, AI en de toekomst van webdevelopment

Almere, 🇳🇱 Netherlands

AI verandert de manier waarop we software ontwikkelen. Tools als Claude Code en Codex worden steeds beter en nemen inmiddels een behoorlijk deel van het programmeerwerk uit handen.

Maar wat betekent dat eigenlijk voor ons als Laravel developers?

Hoe ziet ons werk er over een paar jaar uit? Schrijven we straks überhaupt nog zelf code? Welke vaardigheden blijven belangrijk? En welke kansen en uitdagingen brengt deze ontwikkeling met zich mee?

Binnen de Dutch Laravel Foundation merken we dat deze vragen steeds vaker voorbijkomen. Hoog tijd om daar eens samen over in gesprek te gaan!

Geen presentaties, gewoon goede gesprekken
Geen presentaties, gewoon een informele bijeenkomst met andere like-minded developers om ervaringen, ideeën, zorgen en verwachtingen uit te wisselen.

Of je nu dagelijks met AI werkt, er voorzichtig mee experimenteert of je afvraagt waar het allemaal naartoe gaat: iedereen van de Dutch Laravel Foundation is welkom (besloten bijeenkomst).

Eten wordt geregeld!
We zorgen deze avond ook voor het diner. Je hoeft dus niet vooraf te haasten om zelf nog iets te eten.

Locatie onder voorbehoud
De definitieve locatie bepalen we aan de hand van het aantal aanmeldingen. Deze zal in ieder geval centraal in Nederland liggen. Zodra de locatie vaststaat, laten we dit weten.

Let op: dit is een besloten bijeenkomst voor leden van de Dutch Laravel Foundation.

We zien en spreken jullie graag op dit extra evenement!
