Senior🎓
Top SchoolAntoine Grelety is a Data Scientist and ML Product Lead based in Paris with eight years of experience turning bank transaction data into product-ready intelligence. At PayLead he designs and ships transaction processing and enrichment pipelines, bridging statistical modeling with product requirements to embed ML features in production. His background spans forecasting and optimization projects at EY and analytics roles at Alstom, giving him strong domain grounding in supply chains, pricing and market analysis. Trained in economics and data science (Toulouse School of Economics, ENSEA/ENSAE), he combines rigorous statistical thinking with practical engineering in Python and R. Colleagues value his ability to translate complex models into tangible product value and to operationalize data workflows end-to-end. A less obvious strength is his economist’s instinct for causal interpretation, which helps him prioritize features that drive real business impact.
