I built and deployed Amazon’s production fraud-detection service for abusive seller accounts across international marketplaces, serving real-time inference over 2.5M+ entities.

I designed a multi-signal retrieval architecture using transformer embeddings, HNSW vector search, neighbor-abuse signals, and 74 behavioral features. It reached 99.34% precision and outperformed the previously deployed state-of-the-art model by 2500 bps.

At Indian Oil Corporation’s Guwahati Refinery, I deployed a real-time CCTV safety monitoring system for PPE, fire, and smoke detection using Python, OpenCV, and YOLOv8. I also automated safety logging through REST APIs and SQL, reducing manual inspections by 60% and improving response efficiency by 40%.

I also build collaborative and edge AI products, including CollabHub, a real-time code collaboration platform, and a Jetson TX2 PPE detection system optimized with TensorRT FP16 for 2x faster inference. As General Secretary of the Computer Science Society at NIT Silchar, I’ve led technical events and mentored students in AI/ML and software development.
