Berlin | Fullstack Developer | Serial Side-Project Builder

I've built 20+ side projects. None of them made me rich. I'm still building.

My projects folder looks like the browser tabs of someone who's lost control of their life — mobile apps, SaaS tools, AI experiments, things nobody asked for but I built anyway.

I'm good at making things. Marketing? Let's call it a growth area.
