A real-time distributed chat application built on Android that demonstrates core distributed systems principles in action. The app leverages multiple cloud services working in concert to deliver seamless messaging capabilities.

Architecture Overview: Firebase Authentication - Distributed identity management Firestore/Firebase Realtime Database - Multi-region data synchronization Cloudinary CDN - Global media distribution network Android Client - Edge computing nodes

Distributed Features: Multi-user concurrent sessions with eventual consistency Geo-distributed message replication across Firebase regions Content delivery network for optimized media streaming Decentralized presence management Fault-tolerant image uploads with redundant cloud storage

The system maintains ACID properties for user data while providing BASE semantics for real-time message propagation, showcasing practical CAP theorem implementation in a production mobile environment
