About this project

• Real-time collaborative drawing canvas supporting 40+ concurrent users with sub-50ms WebSocket synchronization, built on the Canvas API with Rough.js for a natural hand-drawn aesthetic.
• Engineered conflict-safe state synchronization so concurrent edits never corrupt shared canvas state, with full drawing history persistence via PostgreSQL.
• Implemented live user presence, cursor tracking, and animated transitions with Framer Motion for a smooth collaborative experience.
