I make maps talk to computers. Based in Switzerland, working at Camptocamp.
Lately I've been teaching LLMs to understand where people mean — "near the lake", "right bank of the Rhône" — and turn that into actual geometry. That's etter.
I've been writing open source geospatial software for 20 years. I help steer OpenLayers and PgRouting as a PSC member, and I'm a voting member of MapLibre.
My usual tools: TypeScript, Python, FastAPI, PostGIS, OpenLayers, LangChain, Docker.
I also build agent skills — reusable AI workflows for things like Swiss tax declarations, OpenLayers automation, and image prompt generation.
