What I'm looking for

I'm looking to apply Power BI, SQL, Python, machine learning, and generative AI to solve business problems, build reliable indicators, and automate analysis and reporting.

At SNCF Voyageurs, I built and deployed self-service Power BI dashboards for five departments, reducing reporting time by 30%. I also developed anomaly-detection models that raised data availability from 60% to 90%.

I've worked across SQL, ETL pipelines, Python, and large datasets exceeding 3 million rows, with a focus on reliable data, clear performance indicators, and business adoption.

As an independent quantitative analyst and Data & AI consultant, I develop temporal-data processing scripts and explore generative AI, RAG, and autonomous agents to automate analysis and reporting.
