Overview
Architected real-time multiplayer platform with AWS microservices backend. Implemented low-latency TCP socket communication (<100ms), server-authoritative game state synchronization, and DynamoDB for persistent world data across all players globally.
Key Features
10K+ concurrent users supported
Server-authoritative state management
Real-time world map synchronization
AWS Lambda microservices architecture
DynamoDB with optimized query patterns
Architecture
C# server application on AWS Lightsail, Node.js Lambda functions for authentication, DynamoDB for player/world state, TCP sockets for real-time communication, OneSignal for push notifications.
