Self-hosting · open source · teaching · photography. Based in Potsdam.
I build sovereign infrastructure, teach what I know, and make images that don't try to sell.
Eight fields where I think, build, and teach.

Kern-Säule
Founding project 2026
Currently being formed: a German limited liability company (UG) as the legal frame for consulting, buildout, operation and teaching of sovereign infrastructure — no license traps, no forced cloud dependencies.
Once the company is registered, it will get its own website. Until then, all business inquiries come directly to me.
Four stations, one line — photography, open source, IT craftsmanship, UG.
My first profession. Architecture, reportage, photogrammetry. Visual language as a tool, not a product.
Linux, in-house tooling, ImageRect, homelab stack. What I build belongs to the community when possible.
Self-hosting, AI integration, security hardening. Systems others can run without me.
Founding project 2026. Legal frame for the consulting work. See above.
No formal degree, lots of practice, a few certifications in the pipeline. Based in Potsdam, working in Berlin-Brandenburg and remote.
