Artificial Intelligence (AI) conference in Krakow, Poland

🚀 BUILD IT CLUB presents:
From enterprise AI adoption to efficient agents and self-hosted inference.
Join us for another exciting AI & Tech Meetup in Kraków, where three speakers will share practical experiences building, integrating, and running AI systems in the real world.

📅 Monday, November 16, 2026
🕡 6:45 PM
📍 Grand Parade, Kotlarska 11, 31-539 Kraków
🎟️ Free event | Everyone is welcome!

AI is changing how we build software, but moving beyond prototypes introduces challenges that go far beyond prompting a language model.
How do organizations integrate AI into their software development lifecycle? How can AI agents become more efficient without wasting thousands of tokens? And what does it actually take to deploy a powerful open-source LLM and build your own coding agent?
This November, we're bringing together three perspectives on the engineering behind modern AI systems.

Data Architect @ Grand Parade
LinkedIn: https://www.linkedin.com/in/irynamarchenko/

Introducing AI across a complex organization exposes gaps in processes, ownership, and documentation.
In this session, Iryna will share how an ongoing AI SDLC pilot is helping address these challenges through shared guardrails, established standards, reusable skills, and human review.
We'll explore how process challenges connect with the technical framework, and how evidence, context, requirements, and design artifacts can form a traceable chain throughout software development.
The current pilot focuses on documentation and design, with implementation and QA planned for the next phase.
What you'll learn:

• The organizational and technical challenges of adopting AI in software development.
• How standards, reusable skills, and human oversight can support AI-assisted workflows.
• Why traceability between requirements, context, and design matters.
• Early lessons from an AI SDLC pilot and the challenges that remain unresolved.

Developer Advocate @ RavenDB
LinkedIn: https://www.linkedin.com/in/weronikakol/

LLM agents are introducing a new kind of workload into our infrastructure.
They may not perform much computation themselves, but they move significant amounts of data. Every request sends context to a model, creating costs in tokens, network traffic, and infrastructure.
Using an open-source hidden-city flight agent running on Kubernetes, Weronika will trace a single question through the system and show how an inefficient architecture can send 40,000 tokens per request, and how that was reduced to approximately 2,500 tokens.
The session explores the evolution of agent architectures, from placing everything directly into prompts to complex RAG pipelines, before simplifying the design through tool calling, push-based communication instead of polling, and a database running inside the cluster.
What you'll learn:

• Why context management matters for AI agent performance and cost.
• How to reduce token usage without unnecessarily sacrificing functionality.
• How architectural decisions affect retrieval traffic and network egress.
• How to measure tokens and bytes per conversation turn.
• Why AI agents need context budgets, just as Kubernetes workloads need resource limits.

Lead Machine Learning Engineer @ Admind Branding & Communication
LinkedIn: https://www.linkedin.com/in/safari-germain/

Everyone is building applications with LLM APIs. But what happens when you want to run the model yourself?
In this hands-on engineering session, Germain will walk through his journey of deploying an open-source language model on local hardware and using it to power a custom AI coding assistant.
Starting with Qwen3.6-35B-A3B NVFP4, a quantized mixture-of-experts model, we'll explore how to serve a large language model using vLLM inside Docker, download and manage model weights from Hugging Face, and expose the model through an API that a coding agent can interact with.
From there, we'll connect the inference server to a Python-based agent engine and renderer, demonstrating how a locally hosted model can power a practical coding assistant without relying on a commercial hosted LLM API for inference.
But running an LLM is only half the story.
We'll also look at the engineering challenges behind inference: model loading, GPU memory constraints, quantization, context length, response latency, and measuring where time is actually spent between the model and the application.
The goal is to show what happens behind the scenes when you move from simply consuming an LLM API to owning and operating the model that powers your application.
What you'll learn:

• How to deploy an open-source LLM locally using Docker and vLLM.
• How quantization helps reduce model memory requirements.
• How to connect a self-hosted LLM to a custom Python coding agent.
• How the model server, agent engine, and user-facing interface work together.
• What affects inference performance, including latency and GPU memory.
• Practical lessons from building and operating your own local AI development tool.

This meetup is for software engineers, ML/AI engineers, data engineers, cloud and platform architects, DevOps/MLOps practitioners, technical leaders, and anyone curious about how AI systems work beyond the demo.
You don't need to be an AI expert. Bring your curiosity, technical questions, and willingness to learn!

• 6:45 PM: Arrival, registration & networking
• 7:00 PM: Iryna Marchenko | AI in the SDLC
  Break at 7:30PM
• 7:35 PM: Weronika Kołodziej | Context Engineering
  Break at 8:05PM
• 8:10 PM: Safari Germain | Local LLMs & Coding Agents
• 8:40 PM onwards: Open discussions & networking

Data / Database conference in Krakow, Poland

On Thursday, November 19th @5:30pm, in cooperation with Keepit, once again we bring you the best meetups in town! We have pizza! We have beer! We have great presentations and all your favorite JS folks in one place!
If you are a senior developer, JavaScript intern, or web apps enthusiast, this meetup is the best way to meet people, make friends, and share and gather new knowledge.
Tell your friends, tell your dog and your neighbors, and see you soon!

Agenda:
👨‍🏫 Jakub Kuś (Fullstack Developer, Rocksoft) - OWASP in practice: From a simple redirect to real-world hacks
Vulnerable code, real attacks, and simple fixes in JavaScript - on frontend and backend.
XSS, SQLI, CSRF, SSRF and some other esoteric shortcuts.
I will show you some real-world stories of how small bugs were chained into full account takeovers at Facebook, Uber and WordPress.

👨‍🏫 Jakub Kasprzyk (Mobile Software Engineer, gmi.software) - How AI Agents Make React Native “Better”
Every React Native app relies on community libraries. We set out to make them faster. Using AI coding agents, we built "Better" versions powered by Nitro Modules, with APIs you already know. In this talk, we’ll explore how AI agents write the native code and, more importantly, how we benchmark it and prove that it’s actually fast.

👨‍🏫 Tymek Zapała (Software Engineer, Cloudinary) – Self-driving product: What does it take for a product to build itself?
We don't write code anymore, so where does software engineering go next? I'll explore one possible direction: building self-driving products that take business objectives and real-world signals as input, independently decide what to improve, implement changes, and evolve toward greater autonomy. Using Cardflow, a real-world SaaS product, I'll show how to build a simple version of such a system, including its architecture, challenges, and safeguards.

👨‍🏫 Marcin Czarkowski (Przeprogramowani) - Jak skalować kontrolę, gdy AI skaluje implementację: lekcje z 10xWorkflow
Od miesięcy słyszymy zapowiedzi autonomicznych fabryk oprogramowania, w których zespoły agentów samodzielnie planują, implementują, testują i dostarczają kolejne zmiany. Rzeczywistość jest jednak znacznie mniej uporządkowana. Trudno w pełni kontrolować nawet pojedynczego agenta - drobna poprawka może skończyć się nieplanowanym refaktorem, testy mogą przechodzić mimo błędnego zachowania, a pozornie rozsądna decyzja techniczna może wprowadzić do projektu zupełnie niepotrzebny dług.

Jeśli więc problemem pozostaje skuteczne delegowanie pracy jednemu agentowi, jak dojść do systemów działających autonomicznie na znacznie większą skalę? I czy pełna autonomia rzeczywiście powinna być naszym celem?

Zobaczysz, jak podchodzimy do tego problemu w 10xDevs i jak nasz framework pozwala koordynować wiele sesji agentów jednocześnie, bez rezygnowania z kontroli nad kluczowymi decyzjami. Pokażemy sposób organizacji pracy, w którym AI może skalować implementację, analizę i wykonywanie zadań, podczas gdy człowiek zachowuje wpływ tam, gdzie jego kontekst, doświadczenie i ocena mają największą wartość.

Hello everyone,
AI keeps raising the bar on what’s possible and how fast it can happen. This edition of techBytes asks a different question. Not how fast can we go - but how do we keep going at all?
We’ll look at it from three angles. Konrad Wadas and Paweł Stobiecki open by proposing a product engineering mindset for deciding what’s actually worth building. Bartek Olejniczak follows with practical job crafting tools to reshape your work before burnout creeps in. And Piotr Szopa closes with a deeply personal story about what climbing a mountain at heart-rate pace taught him about professional (and everyday) longevity.

Key event details - Kraków

• Date: Wednesday, November 25th, starting at 18:00 (6:00 P.M.). Please arrive a bit earlier to grab your seat (around 5:50 P.M.)
• Location: Ocado office, Pawia 21 Street, next to the Main Train Station. Find us on Google Maps.
• Venue: Dedicated event space, 4th floor.

***Agenda***
18:00 - Grab a drink and take a seat
18:05 - Intro

18:10 - 18:40
Speaker: Paweł Stobiecki, Staff Software Engineer & Konrad Wadas, Senior Staff Machine Learning Engineer at Ocado
Topic: Product Engineering: Building what matters in the AI era
Abstract:
Have you ever wondered why, despite all our technological advancements, delivering true value remains a challenge?
For decades, the biggest constraint in software development has shifted: from the sheer difficulty of writing code, to the bottlenecks of testing and deployment. Now, with high-level languages, cloud infrastructure, CI/CD, and the accelerating power of AI, the constraint has moved again. It's no longer how fast we can build, but what we should build - and what we should NOT.
During the talk we'll introduce the role - or rather, a mindset - of a Product Engineer. A mindset that goes beyond just writing code, empowering you to deeply understand the problem, identify user needs, and ensure your technical solution delivers tangible value.
If you're ready to move beyond just writing code and start building things that truly deliver value, this talk is for you. It's time to solve problems, not just ship features.
18:40 - 18:45
BREAK
18:45 - 19:15
Speaker: Bartek Olejniczak, HR Expert & Consultant, Business Trainer
Topic: Before Your Energy Runs Out: What You Can Do to Avoid Burnout
Abstract:
The part of your work that used to give you the most satisfaction is increasingly being done for you by AI.
The pace keeps rising, while the sense that you’re creating something truly yours keeps shrinking. You end the day exhausted, yet it’s getting harder to say what you’re actually proud of.
This isn’t weakness. It may be how burnout begins: quietly, when for a long time we give more to our work than we get back, and our work no longer recharges us the way it once did.
You have more influence over this than you think.
In this talk, I’ll show you how to use job crafting to reshape your work in the age of AI, so you can reclaim what gives it satisfaction and meaning.
I’ll also share what research shows really protects us from burnout day to day. Expect practical tools, no miracle promises, and steps you can put into practice the very next morning.
19:15 - 19:20
BREAK
19:20 - 19:50
Speaker: Piotr Szopa, Senior Product Manager
Topic: Run on Your Heartbeat
Abstract:
You are not unique.
I'm sorry. Your struggles are probably not as unique as you think. We are Poles of a similar age, raised by people shaped by WWII survivors or by the hard years of transformation that followed. That history is not just in books. It lives in us: in how we love, how we work, how we raise our kids, even how we rest. Most of the time we don't notice it, and it rarely makes our lives easier.
I'm a man, a father, and a Mental Wellbeing Champion at Ocado. Over the last few years, those roles made me question patterns I had taken for granted. Then, one September in the Tatras, I tried something simple: I let my heart rate set the pace. I went painfully slowly, and I ended up overtaking everyone.
In this talk, I'll share what that climb taught me: three lessons about feeling more, overthinking less, and why less really is more. You'll leave with one small practice you can try tomorrow morning.
What does any of this have to do with professional longevity? More than you might think.

19:50 - 21:30
Networking over pizza and beer ;)

We are back with raw tech content! The Marine & Ports team invites you to the first ABB TechMeetup in a long time.
When ships are out at sea, hundreds of kilometers from the nearest port, their safety depends on the decisions made by the captain and the engineering crew. For years, our Kraków laboratory has been developing the technologies, software, and integrated systems that support those critical decisions - enhancing vessel reliability, energy efficiency, and operational flexibility worldwide.
We bridge Internet of Things (IoT), automation, advanced data analytics, predictive analytics, and digital services. From remote diagnostics of electrical drives and maintaining IT business continuity across 250+ vessels to R&D on technologies for autonomous ships.
At this meetup, we are opening our doors to share three core engineering perspectives. Expect concrete, no-fluff insights based on real-world experience building solutions that must perform flawlessly across the world's oceans.

2. Andrzej Sadziński - When Code Becomes Cheap: Rethinking Software Quality in the AI Era
AI can generate code faster than any development team in history. As the cost of producing code continues to decrease, the real question becomes: what is still expensive?
In this talk, we'll look at lessons learned from years of maintaining legacy systems, building new products, and making architectural decisions that had to survive long after the original developers left.
We'll discuss why architecture, domain boundaries, trust, and system understanding are becoming the dominant investments in software engineering, and how traditional quality principles evolve when software is increasingly created by machines rather than humans.

Andrzej Sadziński | R&D Principal Engineer/ Software Architect
Andrzej has spent more than 20 years working in software development, systems design, and architecture. He currently works in ABB's Marine and Ports division, where he combines hands-on software engineering with architecture and technical guidance for development teams.

〰️ Marek Szlagor, Staff Infrastructure Engineer at Remitly
From 1 to N: Splitting a Monolith EKS Cluster Without Breaking Production
〰️ Pawel Zapior, Security Engineer at Remitly
Beyond Static Linting: Context-Aware IAM Change Evaluation in AWS

💡 Details about Speakers & Talks💡
Marek Szlagor: Staff Infrastructure Engineer at Remitly whose 13+ year path ran from embedded software through security to cloud infrastructure, now scaling Kubernetes on AWS.

☞ will speak about:
For years, almost everything at Remitly ran on a small set of large Kubernetes clusters. It was simple until it wasn't. Every upgrade became a high-stakes event, one noisy workload could hurt everyone else, and a single bad change could take down the whole platform. For a company moving money around the world 24/7, that wasn't acceptable.

This talk covers how we moved to many clusters on AWS, focusing on what got harder once services no longer shared a cluster: service discovery and security. We'll show how services find and trust each other across EKS clusters, how we enforce least privilege in a highly regulated financial environment, and the lessons we learned the hard way.

Pawel Zapior: Security Engineer at Remitly whose path ran from penetration testing to cloud security, now securing AWS environments at scale. Paweł builds guardrails and automation, convinced that effective security doesn't have to come at the cost of development speed. When he's not securing the cloud, he immerses himself in the world of railways.

☞ will speak about:
Predicting the cloud security blast radius of an infrastructure change using static code analysis is a notorious blind spot. While standard IaC dry-runs show what changes will be made to the resources, they remain context-blind to how those modifications interact with the broader environment. In an IAM context, a single change to the trust policy of an IAM role can implicitly trigger a 4-hop privilege escalation chain across hundreds of AWS accounts, completely invisible to standard static checks.

During this session, we will present a solution that addresses this risk by dynamically evaluating the impact of IAM role configuration changes: a context-aware linter driven by an enterprise-wide identity graph. Ultimately, we would also like this presentation to serve as an inspiration for tackling a similar class of problems: changes that look harmless in isolation but become risky in the context of large, highly regulated and dynamic environments.

Presentation about implementation of Lakehouse Architecture with Medallion Pipelines. The session and Demo will be focused on Data Engineers, looking for starting their early carrier in Data Engineering. If time permits, then we will showcase Genie as well.

+ Prompt Injection vs. Your Database: Break It, Then Lock It - Damian Widera
Giving an LLM agent access to a SQL database means giving that access to anyone who can type into the chat. Instructions like "never reveal other customers' data" in a prompt are not a security boundary.
In this session I attack a text-to-SQL agent running against SQL Server, live. First I exploit it: cross-tenant data leaks, access to restricted columns, indirect injection through a poisoned Notes field, destructive statements, and an unbounded query that burns resources. Then I fix each hole where it belongs, in the database: least-privilege roles on views, Row-Level Security driven by SESSION_CONTEXT, column-level permissions, query limits and audit logging. The same attacks are then replayed against the hardened setup.
