I uncover fraud, risk, and customer insights across large-scale e-commerce marketplaces using data.
IndiaWhat I'm looking for
At Amazon AWS Marketplace, I analyzed 500K+ accounts monthly to uncover behavioral anomalies and emerging fraud patterns. I built dashboards for account health, chargebacks, suspension rates, fraud trends, and operational KPIs, while designing a 50+ rule fraud detection engine.
Previously at Flipkart, I used SQL and Excel to identify quality risks and process gaps, contributing to a 22% reduction in complaint escalations. I enjoy turning large, complex datasets into practical insights through SQL, Python, experimentation, risk scoring, and automated reporting.
