Project Overview

Kaizen To-Do List is a comprehensive task management application designed to help users track their daily progress and maintain motivation through visual feedback. The application combines a clean interface with powerful visualization tools.

Key Features

  • Task Management: Create, edit, delete, and organize tasks with priority levels
  • Heat Map Visualization: Visual representation of daily progress across weeks and months
  • Habit Tracking: Monitor consistency and identify patterns in task completion
  • Motivational Insights: Real-time statistics and achievement tracking
  • Persistent Storage: Data persists across sessions using Local Storage API
  • Responsive Design: Seamless experience across all devices

Technical Implementation

The application was built using React for component-based UI development, ensuring modularity and maintainability. The heat map visualization was created using pure CSS and JavaScript, rendering a dynamic calendar view that updates in real-time.

State management was implemented using React Hooks (useState, useEffect, useContext), providing efficient data flow throughout the application. Local Storage API was leveraged to persist user data without requiring a backend server.

Challenges & Solutions

Challenge: Heat Map Performance

Rendering large heat maps with hundreds of entries caused performance issues.

Solution: Implemented virtualization and lazy loading techniques to render only visible elements, significantly improving performance.

Challenge: Data Persistence

Needed reliable offline storage without a backend infrastructure.

Solution: Utilized Browser Local Storage API with compression techniques to handle large datasets efficiently.

Results & Impact

The final product successfully demonstrates a user-friendly approach to habit tracking. Users report improved motivation and clarity in managing daily tasks. The heat map visualization provides immediate visual feedback on consistency and progress.
