At Optum, I analyze 100M+ healthcare claims across a 20TB warehouse, uncovering anomalies and $800K in duplicate-payment issues. I build Power BI reporting and Python/SQL validation frameworks that raised data accuracy from 94% to 99.2%.
Previously at CVS Health/Aetna, I supported Medicare Advantage claims analytics for 20M+ members and $15B+ in annual claims. I developed dashboards, reconciled EDI claims data, and helped drive $1.2M in annual cost avoidance while reducing eligibility reconciliation from 40 hours to 4 hours weekly.
