Message

At Banco Galicia, I unified TPV data across five payment verticals into a single source of truth, aligning criteria with multiple teams. I automated a daily SQL/Teradata and Power BI dashboard covering around 7 million customers and used by around 100 people.

I also developed a daily Power BI dashboard to track email and push campaign performance by customer type, replacing manual SQL queries with a centralized, comparable history. Earlier, at Biactiva, I analyzed product requirements and validated Teradata databases; at NEORIS, I designed and maintained test cases and reported incidents.
