Real-time JavaScript, end to end.
I'm a full-stack JavaScript engineer with a soft spot for real-time systems. My toolkit centres on Sails.js and WebSockets, the stack behind schnapsen.online, and I build websites and apps for clients across Austria. My code is open source on GitHub.
I've been programming since I was eight. As a kid I wrote MS-DOS programs in QuickBASIC and x86 assembly, later built and ran a browser game with around 200 registered players, and made 3D games with 3D GameStudio. Game development and retro computing never left me. These days I work AI-first, shipping production code with agentic tools like Claude Code and Codex.
Off-screen I'm at the workbench: soldering, 3D printing, and reviving old hardware. You can find my builds in the Electronics Lab.

View build →Animal rights
Every animal is someone, not something.
I'm an animal rights activist. Animals can't speak up for themselves, so I spend part of my free time doing it for them. If you want to know more, just ask. I'm always happy to talk.
tieraktiv.wien
Every upcoming animal-rights action in Vienna on one page: a date-grouped events calendar with subscribable iCal feed, and a newcomer's guide to the different forms of activism.
