I make machines behave. Usually.

Ich baue Infrastruktur aus Neugier, automatisiere aus Prinzip und debugge Dinge, die laut Dokumentation gar nicht kaputt sein können.

The operating manual

I don’t collect tech for the spec sheet. I build systems to understand how they fail — and how to make them calm, useful and a little bit delightful.

Things currently humming

A small digital ecosystem.
Entirely reasonable.

Home lab

3.5TB

NAS storage for important data, questionable backups and files named final_v2_really_final.

~30

Docker containers, each definitely essential.

The process

Production is just a lab with better monitoring.

The weird edge case is usually where the interesting work begins.

Logs, metrics and diagrams. If a system can’t explain itself, it isn’t finished.

Good automation is quiet. It gives people their attention back.

“It’s not a bug.
It’s an undocumented feature.”

— every incident review, eventually
