Message

At Mosambee, I led the design and rollout of ClickHouse as the analytics platform for the payments business, cutting query latency by more than 60%. I also owned transaction anomaly and fraud detection models through production deployment and monitoring, and partnered with product and risk teams to embed predictive scoring in live workflows.

At J.P. Morgan Chase, I built credit card customer segmentation models that lifted campaign conversion by 12% and automated campaign list generation in Python and SQL. Earlier, I worked across data engineering and analytics at L&T Infotech (LTIMindtree), Info-Drive Analytics, and Tata Consultancy Services. I hold an MSc in Data Science & Artificial Intelligence from University of Mumbai.
