01 — About
About me
I'm a fullstack developer based in Antananarivo. I build with Python and FastAPI on the back end and Vue.js on the front, then ship with Docker and GitHub Actions, all from a Linux setup I keep tuning.
Right now I'm going deeper into LLM training and building tools that make developer workflows faster. Off-screen, I practise kendo.
