- Leroy MerlinData Engineer / AnalystOctober 2023 - December 2024 (1 year and 2 months)Lezennes, FranceAt Leroy Merlin, I worked on the Adeo Retail Media (ARM) project to develop an innovative advertising platform. My responsibilities included optimizing data pipelines with Terraform and DLT to reduce costs and ensure smooth transfers between BigQuery, PostgreSQL, and CSV files. I automated quotation processes via Google Sheets, improving the efficiency of exchanges between clients and operational teams. I also designed analytical dashboards to track advertising performance (CPC, CPM) and developed management KPIs for optimized campaign management. Using Looker and LookML, I created interactive visualizations to facilitate data-driven decision-making.
