À propos de moi
I turn scattered data into Power BI reports a business can actually decide with. Seven years doing exactly this inside Santander's technology arm: 10+ dashboards for corporate areas, a Tableau to Power BI migration, and ETL automation that cut manual reporting work by 99 percent.
I build on a proper star schema model, not a flat table, with documented DAX measures and row level security. I also automate recurring reports in SQL, Python and Power Query, and fix slow or untrustworthy reports.
Native Spanish. Intermediate written English.
