Multi-User Collaborative Code Editor
Architected a full-stack live coding platform allowing multiple users to edit code simultaneously. Bridged the gap between complex backend WebSockets (Node.js/Express) and an intuitive frontend React.js interface.

The Goal: Seamless Live Collaboration
The objective was to build a low-latency, real-time environment where multiple developers can write, edit, and debug code together without sync conflicts. The core requirement was a clean, distraction-free user interface that handles complex backend data without overwhelming the user.

The Challenge: State Management & UI Sync
The biggest UX challenge was handling real-time cursor tracking and simultaneous keystrokes without UI lag. I implemented WebSockets (Socket.io) for instant bi-directional data transfer and designed intuitive visual cues—like Figma-style coloured cursors and name tags—to clearly differentiate active users in the workspace.
