Overview
Built a real-time collaborative document editor using CRDTs for conflict-free synchronization across multiple users.

Results & Impact
Supported 50+ simultaneous editors per document with sub-100ms sync latency.
Key Learnings
Mastered CRDTs, WebSocket optimization, and building resilient real-time systems.
