TaskFlow
A real-time project management application designed for small to mid-size teams who want Kanban-style workflow without the bloat.
Features
- Real-time collaboration via WebSocket connections — see teammate cursors and card movements live
- Kanban boards with drag-and-drop, swimlanes, and custom columns
- Team analytics showing velocity, cycle time, and workload distribution
- Markdown-based card descriptions with rich previews
Technical Highlights
The backend runs on Node.js with PostgreSQL, using a pub/sub pattern for real-time events. The frontend is a React SPA with optimistic updates for snappy interactions.
Authentication uses JWT tokens with refresh rotation, and the API follows RESTful conventions with consistent error handling.
Lessons Learned
Building real-time features is harder than it looks — conflict resolution, reconnection logic, and state synchronization all need careful thought. But the result is a dramatically better user experience.
