Leading the development team of mailbox.org. Currently shaping the way we work: cross-functional teams, focus iterations, and a rotating point person for critical tasks, protecting everyone else's focus. Maturing our OKRs into a meaningful framework: fewer, sharper objectives, with the first measurable results coming in.

And trying a lot with AI right now. Beyond Copilot and Junie in the code, every process around it gets an AI-supported rework: code review, QA, post-mortems, even use cases generated from the source code. Some experiments stick, some don't. We keep what works.

More and more of my spare time goes into motion graphics for buecherhausen.de, my wife's book blog. Home Assistant tinkering, now with MCP and AI in the mix, garden projects, WoW MoP Classic with the guild, and testing new cooking and BBQ recipes whenever I get the chance. Lately going deeper into chess, and back into fantasy: The Last Unicorn and Le Guin's first Earthsea trilogy are done, and right now I'm completely hooked on Lee Young-do's The Bird That Drinks Tears. My shelf has the rest.

Still rage-quitting LinkedIn and other feeds after too many bad AI images. Too many = one or two.

Small things I built, all vanilla: no framework, no build step, no third-party requests. Put together the same way as this site.

Bookaholic is a quiz for my wife's book blog buecherhausen.de: how book-addicted are you? Anonymous statistics without any personal data, and a result image to share. Live
