A modern, intuitive task management tool built for remote teams. Features real-time collaboration, customizable workflows, and beautiful UI.

Overview

TaskFlow was born out of frustration with existing project management tools being either too complex or lacking essential features. I built a solution that’s powerful yet simple to use.

Key Features

Core Functionality

  • Kanban Boards - Drag-and-drop interface for visual task management
  • Real-Time Sync - See changes instantly as team members update tasks
  • Multiple Views - Switch between Kanban, List, and Calendar views
  • Task Details - Rich descriptions, attachments, comments, and checklists
  • Labels & Filters - Organize and find tasks quickly

Collaboration

  • Team Workspaces - Separate spaces for different projects/teams
  • @Mentions - Tag team members in comments for notifications
  • Activity Feed - Track all changes and updates
  • Permissions - Role-based access control (admin, member, viewer)

Productivity

  • Keyboard Shortcuts - Power user features for faster navigation
  • Templates - Reusable board templates for common workflows
  • Due Dates & Reminders - Never miss a deadline
  • Time Tracking - Built-in timer for task duration tracking

Technical Implementation

Real-Time Features

Used WebSockets (Socket.io) for instant updates across all connected clients. Implemented optimistic UI updates for snappy user experience even before server confirmation.

Drag & Drop

Built custom drag-and-drop using react-beautiful-dnd with smooth animations and mobile touch support.

Performance

  • Implemented virtual scrolling for boards with 1000+ tasks
  • Optimized database queries with proper indexing
  • Used Redis for session storage and caching
  • Image optimization with Next.js Image component

Authentication

  • Secure auth with NextAuth.js
  • Support for email/password and OAuth (Google, GitHub)
  • JWT tokens with automatic refresh

Architecture

Built as a modern monolith with Next.js API routes:

┌─────────────┐     ┌──────────────┐     ┌─────────────┐
│  Next.js    │────▶│   API Routes │────▶│ PostgreSQL  │
│  (React)    │     │  (REST/WS)   │     │  + Prisma   │
└─────────────┘     └──────────────┘     └─────────────┘
       │                    │
       │             ┌──────▼───────┐
       └────────────▶│  Socket.io   │
                     │  (Real-Time) │
                     └──────────────┘

Challenges Solved

Real-Time Conflicts

Problem: Multiple users editing same task simultaneously

Solution: Implemented operational transformation (OT) for conflict resolution and last-write-wins strategy with conflict notifications

Mobile Performance

Problem: Drag-and-drop laggy on mobile devices

Solution: Optimized touch handlers and reduced re-renders using React.memo and useMemo

Scale

Problem: Growing user base causing performance issues

Solution: Added Redis caching layer and optimized database queries, reducing response time by 65%

Results

  • 📈 Users: 2000+ active users within 3 months
  • Product Hunt: Featured and received 200+ upvotes
  • 🚀 Performance: Sub-100ms API response times
  • 💯 Uptime: 99.8% uptime since launch
  • 📱 Mobile: 40% of traffic from mobile devices
