At Wizzmind, I redesigned a 1 GB monolithic Power BI model for Crédit Agricole into per-domain star schemas, restoring performance on the same servers without a hardware upgrade. I also implemented row-level security and consolidated security data in SQL Server.
At Tata Consultancy Services, I owned Infineon's shared sales analytics model, from the dimensional datamart to the SSAS semantic layer, and cut monthly processing time by about 40% by refactoring and indexing heavy queries. Earlier, I built a marketing reporting platform at Lingaro and designed a SQL Server data warehouse and datamarts at Grupo Avalon.
