Backend Architecture

  • RESTful API - Express.js with TypeScript
  • WebSocket Server - Socket.io for real-time features
  • Authentication - JWT with refresh tokens
  • Database - MongoDB with Mongoose ODM
  • Caching - Redis for performance

Real-time Sync

Implemented WebSocket connections for real-time updates:

// WebSocket event handling
socket.on('task:update', (task) => {
  updateTaskInState(task)
  notifyRelevantUsers(task)
})

Challenges & Solutions

Challenge 1: Real-time Sync Conflicts

Problem: Multiple users editing the same task simultaneously Solution: Implemented operational transformation algorithm for conflict resolution

Challenge 2: Performance with Large Datasets

Problem: Slow load times with thousands of tasks Solution: Virtual scrolling and pagination with infinite scroll

Challenge 3: Offline Functionality

Problem: Users needed to work offline Solution: Implemented service workers and IndexedDB for offline support

Performance Metrics

  • Load Time: < 2 seconds
  • Time to Interactive: < 3 seconds
  • Real-time Latency: < 100ms
  • Concurrent Users: Supports 1000+ simultaneous users

Security Features

  • Data Encryption - AES-256 for sensitive data
  • HTTPS Only - Enforced SSL/TLS
  • Rate Limiting - Prevent API abuse
  • Input Validation - Prevent injection attacks
  • CORS Configuration - Secure cross-origin requests

Deployment

Infrastructure

  • Frontend: Vercel for React app
  • Backend: AWS EC2 with load balancer
  • Database: MongoDB Atlas
  • Cache: Redis Cloud
  • CDN: CloudFront for static assets
