About me

I'm in my final year of computer science at Universität Siegen. Most of what I know comes from building and shipping my own projects: a real-time multiplayer game, a desktop PDF library, a 3D globe, and now Pantrio, which I'm building on my own from idea to production.

I'm looking for a Werkstudent role in a team where I can work on real tickets, get my code reviewed and keep growing as an engineer. I can work 20 hours a week, on-site in NRW or remotely.
