About me
Developer since my IT apprenticeship in 2017, day job on the City of Vienna's digital team.
More than four years of professional fullstack work: TypeScript with Angular and React on the front end, plus mobile apps with Ionic and Capacitor; NestJS and Java with Spring Boot and Hibernate on the back end. I also build web apps in my own projects (e.g. b-cal).
Since May 2026 I have been running my own system of AI agents based on Claude and OpenClaw: it plans my day, rates the links I collect, watches my servers and writes code with me. I build agentically with Claude Code and review its code like a colleague's.
I prefer projects meant to last longer than a quarter: cleanly built, self-hosted on infrastructure I manage end-to-end, with tools I'll still trust in two years.
