United StatesWhat I'm looking for
I’m a Data Analyst with 2 years of experience across financial services and pharmaceutical analytics, focused on turning messy data into reliable decisions. I combine advanced SQL, Python (including ML), and BI tools to deliver fraud and spend-pattern insights while keeping pipelines audit-ready.
In my recent work at Bank of America, I processed 500K+ monthly transactions, built natural-language dashboards that reduced ad-hoc requests by 35%, and improved anomaly detection with 86% fraud detection precision. I also maintained GDPR/CCPA-compliant data lineage across 15 tables and enforced data quality with Great Expectations. Previously at Dr. Reddy's Laboratories, I unified scattered sales data, accelerated reporting from 3 hours to 20 minutes, and achieved 88% forecast accuracy using Prophet and ARIMA.
