About

I started my journey in tech not with a computer science degree, but with a need to rebuild. After facing significant personal challenges, I dedicated myself to learning how to build. What followed was a year of intense, focused work.

Today, I specialize in building full‑stack AI applications for the European market, with a deep understanding of the logistical and regulatory challenges (GDPR, SGB XI) that matter here. My work on Hausheld, a complete workflow system for a 200‑employee home‑help service in NRW, is a testament to my ability to turn a complex, real‑world 'logistical nightmare' into a clean, production‑ready digital platform.

I don't just write code. I build systems that work for people.
