Hi, I'm Henrik.
I'm a CS student, developer and freeride skier from Germany. I study Media Informatics & Business Administration at the University of Regensburg.
I build things I actually want to use — from ELO ranking apps for friends to low-level TCP port scanners in pure C. I also organize large campus events and serve as an elected student representative for 1000+ students.
When I'm not coding, I'm skiing the backcountry with Red Bull athletes, designing posters in Illustrator, or winning Java competitions.
Open to internships, collabs & interesting projects.
Before I wrote code,
I made posters.
Fan poster designs for Eminem, Travis Scott, and Thomas Müller. Still do, sometimes.
Adobe Illustrator & Photoshop. Almost went to design school — discovered coding instead. Now I do both.
