At Itaú Unibanco, I supported Open Banking initiatives by enhancing SQL-driven data architecture and designing extraction, transformation, and validation frameworks for high-volume transactional data.
For PIX, Brazil's instant payment ecosystem, I supported analytics initiatives and designed data models for consistent reporting and KPI analysis. I also developed analytical solutions in AWS QuickSight and Power BI for revenue analysis, customer segmentation, and operational KPIs.
I automated reporting and data-processing workflows, reducing manual processing effort by approximately 90%. My work also included strengthening data validation and reconciliation, and I contributed to a 12% reduction in operational expenses through analysis of operational and financial data.
