Hi — I'm Sönke, a software developer from Lübeck. I like the small details — in a cup of coffee, on a bike, or through a viewfinder.
Most mornings start with a pour-over and a few tasting notes. Most weekends involve a steel road bike and as much open road as I can find.
And somewhere in between there's always a camera within reach, for the small, fast-moving moments I'm forever trying to hold onto.
Mostly MCP servers that teach Claude new tricks — plus the occasional bit of hardware.

A pair of ESP32 walkie-talkies on M5Stick hardware, built for my kids — soldering, C++ and two very happy field testers.
Three things keep me sane. None of them involve a deadline.
Filter, almost always. I brew on a V60 or my OXO rapid brewer and keep a few tasting notes. The goal each morning: a cup that tastes like more than just "coffee".
Long roads on a steel-framed Fairlight Strael 3.0. Steel because it soaks up the rough stuff and gives a little back, which feels about right for a bike that's mostly about clearing my head.
I shoot Fujifilm — mostly light, texture and small everyday scenes. The camera makes me slow down and actually look at things.
A few frames I keep coming back to — home, farther out, and the world through wet glass.
