Work experience

Senior Data Scientist at Goldman Sachs, Bengaluru, Karnataka, India, In my current role at PayU Payments, I have spearheaded the development of a comprehensive merchant fraud risk monitoring system, which includes model development, rule design, and performance validation. I have successfully built supervised machine learning models using CatBoost and XGBoost, achieving impressive precision and recall rates. My work involves analyzing vast datasets of merchant transactions to design impactful risk rules, significantly enhancing fraud detection capabilities. Additionally, I have designed a centralized feature store that integrates numerous engineered features, thereby improving the efficiency of model lifecycle workflows across the team. Achievements: My contributions have led to a remarkable 96% recall rate in fraud detection, resulting in monthly savings of approximately 1 Cr. I have also developed an unsupervised fraud detection model that has the potential to save around 2 Cr per month. My efforts in identifying monitoring gaps have reduced losses by 75%, and I have successfully integrated merchant alerts with the CRM system, which has significantly improved response times to high-risk incidents. Furthermore, I received the PayU Payments Data R&R Award for establishing the end-to-end framework of the Merchant Fraud Monitoring System, which has greatly enhanced organizational risk governance.
