Data analyst / data scientist for nearly 4 years, I transform your data into concrete levers for the company.
Through my experiences, I have contributed to tripling the speed of processing pipelines (20min → 7min), guiding the strategy of a conversational agent to reach inactive users, and improving data quality by identifying governance gaps and promoting the implementation of best practices.
My approach combines technical expertise and business vision: each project is designed to produce tangible, measurable results that are directly usable by your teams.
