Description

Certified Microsoft Senior Data Analyst with over 12 years of experience transforming complex data into strategic levers, particularly in the banking, luxury, and energy sectors. I undertake projects ranging from smart grids and forecasting models to the implementation of enterprise-wide BI solutions, combining technical expertise with business vision.

My proficiency in Power BI, SQL, Databricks, SSAS, and R/Python has enabled me to successfully support major groups such as L'Oréal, Société Générale, BPCE, and several national energy players.

Passionate about data storytelling and informed decision-making, I design dashboards that are clear, performant, and focused on users' real needs—not just indicators.
