About this gig

I've built real-time chat systems from scratch for consultation platforms handling thousands of concurrent users using WebSockets, Firebase Realtime DB, and Sendbird depending on the use case.

The hard part isn't sending a message it's handling reconnection on poor networks, message ordering under load, and graceful degradation when the connection drops. I've solved these in production across multiple apps.


Stacks I work with: WebSocket + OkHttp, Firebase Realtime DB, Sendbird SDK

Tell me your backend stack when you message I'll recommend the right approach.
