Who I am

I'm Jean de Dieu, a backend developer based in Lomé, Togo. I specialize in building APIs and intelligent systems — from secure authentication to AI-powered matching engines. I'm also the co-founder of Kizo, an event platform I built from the ground up.

Finishing a Master's in AI & Big Data. My Mechanical Engineering background trained me to think in systems — constraints, tradeoffs, failure modes — which shows in how I design and build software.
