About
From Bern, studied CS in Biel, living in Zurich. Spent 25 years in Swiss banking, now I build my own things full-time. Schwitzerdütsch and English.
When I'm not coding: family with two kids, mountain bike, ski, hike, gym.
Databases
Oracle is where I spent most of my career. PL/SQL, performance tuning, the whole stack.
Full Stack
Node.js is my go-to. I run everything on Linux with Nginx and PM2.
AI Integration
I wire up LLMs into everything now. Multiple providers, voice, images.

25 years of regulatory reporting and Avaloq in Swiss banking.
