Dominic Buchheit
Senior Software Engineer · Saarland, Germany
Backend-leaning full stack. Elegant systems, self-hosting, and tools that respect the people using them.
About
The short version. The long one lives in the CV.
Building software professionally since 2012 — most of it at Software AG, where I led the technical side of large globalization projects, and since January 2026 at Extrain.io. Full stack, with the weight on complex backend systems and getting them deployed, these days with AI in the toolchain.
I am not loyal to any one stack — choosing the one that fits the problem is the part I enjoy. Outside work I build small, privacy-minded things and host them myself, on the machine that serves this page.
Projects
Small things I built and still run.

Send a secret that destroys itself after a single read. Encrypted in the browser, so the server never sees it. Open source, so you can check that.

Leave a note at a place. Other people only see it once they are close enough. React and Supabase, still a work in progress.
