Building high throughput backend systems for real time video, IoT data, machine learning validation, and geospatial processing across India's mobility ecosystem.

• ›Architected and deployed a real time video streaming and two way audio communication system using Go, FFmpeg, and EMQX (MQTT), ingesting and processing binary IoT streams at 300 GB/day (9 TB/month).
• ›Deployed ML models and built Python based Kafka consumers with Celery for background processing to validate 1M+ IoT generated alert images daily, filtering 70K+ noisy or invalid alerts to reduce false positives.
• ›Developed a high throughput geofencing system using Node.js, TypeScript, PostgreSQL/PostGIS, and MongoDB to evaluate 20M+ GPS pings each day through real time spatial queries and low latency alerting.
• ›Engineered a distributed image to video pipeline that processed 200K+ images each day, orchestrating frame sequencing and efficient video stitching through parallel, asynchronous execution.
