Introduction
Data Science Manager with 10+ years leading data science teams (up to 6 people) across mobility, healthtech and industry, from Python ML pipelines to GenAI products. I build teams from scratch, ship ML products end-to-end, and cut time-to-market by 50% through better workflows and cross-functional alignment. Pragmatic and people-focused, I grow data scientists and ML engineers and turn ambiguous problems into working products. Engineering background: École polytechnique, Mines ParisTech.
