At VersionX, I built the STOPS driver and conductor app and its event-driven trip lifecycle using Firebase RTDB triggers, Node.js Cloud Functions, and PostgreSQL stored procedures. The platform supports 1L+ users and 50K+ daily pickup and drop events.
I made pickup scans durable through connectivity drops with offline-first IndexedDB sync and conflict resolution, and added live GPS streaming, geofencing, and alert routing. I also worked on QR/NFC guardian authentication and a shared tags system used across platform modules.
At Jio Platforms Limited, I built Node.js REST APIs for JioMart coupon management and used Redis caching to cut response time by 25%. I also developed React screens and Node.js APIs for an internal asset management system, improving query speed through PostgreSQL indexing and schema changes.
