Multi-User Document & Canvas Collaboration Engine
Conflict-free replicated data type (CRDT) engine powering sub-15ms multi-user collaborative editing.
System Context & Operational Scope
A high-performance real-time synchronization backend and interactive canvas built for engineering diagrams, flowcharts, and technical notes.
Traditional operational transformation (OT) protocols struggled with network splits and offline mutations, causing lost annotations during engineering team reviews.
Core Engineering Objectives
- Enable seamless offline drawing and zero-conflict multi-peer merging.
- Keep network sync overhead under 25 bytes per cursor movement.
- Scale room sessions to 100+ simultaneous collaborators.
Verified Performance Metrics
Technologies Used
Architectural Strategy
Implemented Yjs CRDT state trees synchronized over binary WebSocket frames, managed by an epoll-based Go coordinator and ephemeral Redis cluster.
Implementation Details
An ultra-fluid web canvas with peer presence avatars, selective undo/redo history, and vector SVG exporting capabilities.
