Hi, I'm Vincent Demeester
I'm a french developer 🐻, Gopher 🐹, sysadmin 🐺, factotum 🦁, free-software fan 👼 and unicode lover 🐸. I'm working RedHat 🎩 as a principal software engineer, previously at Docker 🐳 and Zenika 🐯. I am a maintainer of the docker project (
docker/cli, …), the TektonCD project (
tektoncd/*) and a tiny bit of NixOS.
