The Scale

ConnectSocial needed a messaging app with sub-100ms message delivery, end-to-end encryption, and the ability to handle group chats of up to 1000 members simultaneously.

I built a Flutter app backed by a Go WebSocket server for real-time messaging, with Signal Protocol for E2E encryption and a custom CDN pipeline for media delivery.
