I build backends where events happen instantly — live location tracking, multiplayer sync, real-time notifications, chat systems, and collaborative tools. No polling. No delays. True real-time.

My proof: Built the Socket.IO layer for a full ride-hailing platform — live captain location broadcast, instant ride confirmation events, OTP-verified ride start, and graceful disconnect/reconnect handling. Also built the WebSocket backbone for a multiplayer metaverse game, handling position sync for multiple concurrent users in shared spaces.

What I deliver: → Socket.IO or native WebSocket (ws) server architecture → Room-based and broadcast event systems → Auth-protected socket connections — JWT verified on handshake → Live data: location tracking, chat, collaborative state, game position sync → Graceful disconnect detection and session restore on reconnect → Integration with PostgreSQL or MongoDB for persistent event history → Load-tested and latency-optimized — sub-second event delivery

If your product needs any kind of live, push-based data — I've built it.
