Description

Specialized in Business Intelligence, I have developed expertise in data transformation and processing. I support large companies in modernizing their decision-making ecosystem. I combine historical expertise in the Microsoft BI suite (SSIS/SSAS/SSRS) with advanced mastery of Azure and Databricks cloud environments. I also master the entire value chain: from business scoping and architecture design (DataVault or star modeling) to production deployment in Agile environments (Safe, Scrum). I guarantee the optimization of performance and the reliability of data flows. Certified Azure Data Engineer, MCSE, and MCSA SQL Server, I bring technical rigor and a "Data Ops" vision (CI/CD) to every project.
