Senior full-stack engineer in Amsterdam. Fifteen years of building products end to end — mostly the front-end, but I own the API and the infrastructure under it when that is what the product needs.
Most at home in TypeScript and Node.js: ten years of Angular, five of React and the TanStack ecosystem, Fastify and PostgreSQL on the server, and Rust with Axum for the parts that need it. I like taking technical ownership of a product: setting its direction, then making it fast and obvious to use.
Right now I run NootropicsIndex, a price comparison platform I built and still maintain a TypeScript monorepo of eight services, a Playwright crawling pipeline across 16+ storefronts, and a gated classifier on a locally hosted LLM.
On the side I am currently modifying the firmware of my Samsung Odyssey OLED G9 (G93SC) to unlock advanced motion clarity features. Work in progress in the open at g93sc-firmware-mod. worth watching if you have the same panel.
Previously at Bitonic, FunXtion, BBN Adviseurs, Geodan and NEP.
