# DropRoom Mobile & Backend

DropRoom is a high-performance, cross-platform, real-time messaging application featuring secure authentication, live chat rooms, and dynamic profile synchronizations. The ecosystem splits cleanly into a compiled, stateful Go WebSocket engine deployed on AWS and a highly responsive React Native mobile app built with Expo.

DropRoom is not just a chat app; it is a demonstration of handling stateful, high-throughput real-time data across mobile clients. By moving away from standard BaaS platforms (like Firebase) and engineering a custom WebSocket pipeline in Go, DropRoom achieves minimal latency, extreme horizontal scalability, and seamless cross-platform native performance.
