About Nicolas

PhD-educated data scientist with expertise in advanced modeling, forecasting, and spatio-temporal data. I can also adapt to broader needs: framing data problems, data preparation and quality, classical modeling (regression, classification, time series), experimentation, light production deployment, and results communication. I work pragmatically, integrating with teams and respecting contextual constraints (data, deadlines, tools), with a focus on useful and evaluated deliverables.
