Software Engineering Events in Ljubljana
This is the widest category on Brainberg, because software engineering itself spans a huge range of events: language user groups (Python, Rust, Go, TypeScript, Kotlin, Elixir, Ruby, Zig), framework communities (React, Svelte, Next.js, Vue, Laravel, Django, NixOS), backend architecture tracks, testing and QA tracks (ISTQB certification courses, mutation testing, test-automation workshops), refactoring and DDD circles, hackathons, and the long tail of "thoughtful engineering" meetups that don't fit neatly under any specific stack.
This page narrows the Ljubljana calendar to Software Engineering events. It's a subset of Slovenia's wider tech-event schedule, useful when you want something specific to go to in the city this month.

Ruby meetup Q2
Ljubljana, 🇸🇮 Slovenia
We're thrilled to announce the next edition of the Slovenia Ruby User Group meetup! 💎🇸🇮
Mark your calendar on Thursday, June 11th, 2026, we'll be gathering from 18:00 to 20:00 at Računalniški muzej / Computer History Museum Slovenia.
We'll have Luka Ločniškar talk about LLM integration at Scania.
We'll be continuing with the "alternative format":
- Show-and-tell
- Open floor discussion
This means that the content of this meetup is entirely up to the attendees!
Have an interesting project you'd like to talk about? Bring it along! Got a technical problem you'd like to discuss? Bring it up! Got new approaches on your mind? Don't be afraid to challenge the status quo!
As always, we’re keeping the floor open for any lightning talks. If you have an idea, a project, or a Ruby gem you're passionate about, bring it along!
Post the knowledge exchange, we'll go for food and drinks.
Whether you're a seasoned Ruby professional, a newbie who's just getting started, or anywhere in between, this is the place for you.
Don't miss out on Ruby meetup!
We can't wait to see you there.
How Product Leaders Decide What Not to Build
Ljubljana, 🇸🇮 Slovenia
Building a great product isn’t just about adding new features. It is about having the discipline and clarity to decide exactly what not to build.
At this meetup, we will dive into how product leaders make high-stakes prioritization decisions in two entirely opposite environments: a massive global enterprise and a fast-moving, VC-backed AI startup.
The Speakers & Contexts
Andraž Zvonar, Founder & CEO at KatalistAI – A fast-growing AI platform that automates professional video production from script to screen. The company recently secured $1.5 million in VC funding from South Central Ventures and already boasts over 300,000 registered users worldwide. Andraž has been a product manager before starting KatalistAI.
Matej Kern Meglič, Product Manager at Teads – Representing a global media and adtech giant operating one of its core European engineering hubs right here in Ljubljana. With over 40 Product Managers collaborating worldwide, Matej will share how they manage massive corporate roadmaps and balance endless competing demands without creating organizational deadlock.
What We Will Cover
- We’ll skip the textbook theories and dive straight into the messy reality of product operations:
- Planning vs. Chaos: Structured roadmaps vs. early-stage startup agility.
- The Reality of a Pivot: What shifting directions actually looks like under pressure.
- Operations & Legacy Debt: Managing technical debt, iteration speed, and structured agile vs. pure ad-hoc teamwork.
- The Art of Saying NO: Standing your ground against corporate stakeholders, enterprise clients, or demanding VC investors.
Event Details
Where: Gecko HRM, Letališka 32, Ljubljana
When: 16 June, 18.00-21.00
Vibe: Fireside chat, open audience Q&A, and informal networking with pizza and drinks.

🗣️ Big Data, Bigger Lessons
Tilen Kavčič - Senior Software Engineer @ Outfit7
5 billion events a day. 200 million monthly players. Two clouds, one data team.
Tilen will walks us through how Outfit7 built a data platform that had to keep up with one of the world's most-played mobile game portfolios, covering ingestion at scale, pipeline orchestration, the move to dbt, and what it actually means to run a parallel data warehouse on Huawei Cloud for Chinese users.
Practical war stories. No architecture astronauts.
🗣️ Maintainability is a Feeling
Miha Medven – Senior Engineering Manager @ Sportradar
Introducing new technologies into an existing stack is rarely just a technical problem. The real challenge is building confidence: confidence in operability, debugging, scalability, onboarding, and long-term maintenance. This talk explores practical ways to evaluate, introduce, and operationalize new technologies in backend systems without turning your stack into a liability.
👥 Who should come?
Open to developers, engineers, architects, students, and anyone interested in backend technologies.
Expect discussions around scaling systems, introducing new technologies responsibly, operating data platforms in production, and the engineering tradeoffs behind it all.
All sessions will be in English 🇬🇧
See you there 👋
