À propos

Introduction

Freelance for 4 years, I have had the opportunity to support numerous companies and public organizations, including Sanofi, ACTEE, Kallista Energy, Clint, and L'HAS. Specialized in data integration via API systems within an ETL framework, I work across the full data pipeline: from sourcing and extracting data from external systems, to processing and structuring large datasets, and delivering actionable insights through KPIs and dashboards.
