Brainberg

Software Engineering Events in Brussels

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 Brussels calendar to Software Engineering events. It's a subset of Belgium's wider tech-event schedule, useful when you want something specific to go to in the city this month.

Brussels is unusually weighted toward tech-policy and open-source events because of the EU institutions concentrated in the city. FOSDEM each February is one of the largest open-source conferences in the world and draws tens of thousands. Around it, the calendar is full of AI-governance, data-protection, cybersecurity-policy, and platform-regulation events that reflect Brussels' role as the policy capital of European tech.

Becoming a Freelancer in Tech

Brussels, 🇧🇪 Belgium

Thinking about freelancing in tech? Get honest insights on finding assignments, building your network, and getting started.

Thinking about freelancing in tech? Or already started, but still figuring things out? This event is for people who want to become freelancers and for freelancers who are still in the early phase of their journey.

Because starting out is about more than making the leap. It is about knowing how to find assignments, how to build your network, and how to create a freelance career that fits you.

During this evening, you will hear an honest and relatable story from Karen De Bock, a digital professional with more than 20 years of experience in design, front end development, project management, client strategy, and leadership.

Karen started her career as an employee, then moved into freelance work to gain more freedom, flexibility, and variety. What started as solo freelance work later grew into a company of around 25 people. After selling that business around the COVID period, she is now returning to freelancing with a fresh perspective, focusing on project management, coaching, and guiding people through change.

Her story is interesting because it is real. No polished guru story. Just practical experience, honest lessons, and a career path that evolved over time.

What to expect
  • Practical insights on becoming a freelancer in tech
  • Inspiration from a speaker with real life experience
  • Tips on finding assignments and growing your network
  • Time for Q&A and networking with others in a similar phase
For who?
  • People who want to become freelancers in tech
  • Freelancers who recently started
  • Professionals exploring the move from employee to freelancer
