• Architected a Video Management System serving 240+ cameras and 100+ concurrent live streams (8 streams/GPU core) at <500ms latency, leading a team of 5 to ship live recorder UI, camera onboarding/validation, and a dynamic profile configurator — built with Angular, RxJS, Node.js/Express, and MongoDB. • Redesigned the data layer to ingest 2M+ records/day via MongoDB denormalization, aggregation pipelines, strategic indexing, and Change Streams — maintaining sub-second UI performance while eliminating fetch bottlenecks at scale. • Engineered frame-accurate HLS/gRPC synchronization using custom proto definitions for pixel-perfect ROI overlays on live surveillance feeds; built a video summarization orchestration layer with on-demand Kubernetes pods, real-time WebSocket progress tracking, and Kafka event streaming. • Developed a geospatial command center in Leaflet.js plotting 240+ cameras via lat/long with animated ripple alerts and contextual popups; shipped a Google Calendar-style task scheduler with Agenda/cron and auto-recovery across Kubernetes pod restarts, plus a reusable Angular component library with an interactive image comparison toolkit (overlay, side-by-side, drag-to-compare, chessboard tile-grid) and collapsible treeview.

•Utilized advanced algorithms such as recursion, map set, and graph to streamline record fetching process, reducing retrieval time by 90% and improving overall user experience. • Implemented innovative techniques to decrease the size of generated PDFs by 80%, enhancing file storage efficiency and reducing bandwidth usage. • Optimized React application with Node backend and SQL DB to efficiently handle 20-50 million data records per day, resulting in improved application performance and reduced server load by 70%. • Building a live media server that converts camera RTSP feeds to RTMP, enabling web browser streaming. • Bolstering security with rate limiting, token authentication, and SQL injection defenses.
