Software developer building useful things
across systems, apps, and the web.

01 / about

I like knowing how things work.

I’m a software developer and IT Systems Engineering student at the Hasso Plattner Institute in Potsdam.

I enjoy working close to the metal, from C and C++ to cross-platform applications with Flutter. I’m especially drawn to security, automation, and open-source software.

This is where I keep a small record of what I build, learn, and find worth writing down.
