At EXL Services, I own daily SQL-based data validation and reporting for a $60M/month US banking portfolio across DDA, credit card, mortgage, transaction, and inquiry data. I identify anomalies, validate source-to-output tables, and partner with data engineering and business teams to improve data reliability, helping avoid overpayments by nearly 80% and reduce payout discrepancies by approximately 60%.
I've also optimized real-time fraud strategies for card and money-movement portfolios, migrating SAS workflows to Python and PySpark to cut processing time by 30–50% and storage usage by about 50%. I build Tableau KPI dashboards and automated catch-up processes that prevent data-load failures from reaching downstream reporting.
