01 — About

Built for teams
that need real results

I’m a Python and automation engineer based in Hamburg. I build backend systems that eliminate manual work — AI agents, CRM integrations, data pipelines, and workflows that run without supervision.

My infrastructure runs on private Hetzner servers. Every project is self-hosted by default: your data stays on your infrastructure, not in someone else’s cloud — and that’s the starting point, not an afterthought. Also available for Make.com and Zapier projects.

Every automation I deliver is documented, monitored, and designed so your team understands it without needing me on call every week. The goal is to hand over something that works independently.
