Overview
Agentic Engineer @Tandem
About
- Breton-born, Paris-based JS/TS engineer. I like products that ship and code that won't make me wince in six months.
- Founding engineer at Tandem, building the web product. Before that, co-founded Qeels and ran engineering for two years.
- Studied at 42 Paris — mostly C, processes, and sockets. Still helps when a Node bug turns out to live a layer below.
- Stack I reach for: TypeScript, React, Next.js, React Native/Expo, Node, Bun, NestJS, Postgres, Docker.
- Side experiments and half-finished ideas live at github.com/Untel.
