At Programming.com, I built a real-time fraud detection engine that cut COD fraud losses by 90%, along with an event-driven risk pipeline processing 10k profiles daily. I also optimized a color-extraction pipeline 35x and led an OpenTelemetry migration across 15+ services.

Previously, I built backend services and REST APIs for retail brands including L'Oreal, Coach, and Ralph Lauren at Publicis Sapient, delivering UGC, recommendations, product badging, and notifications that increased engagement. I work with Node.js, Express.js, Kafka, MongoDB, Docker, and distributed systems.
