- User reviews and accepts or modifies priority
- Task is added to the prioritized list
Daily Task Review:
- User opens app to view daily task list
- AI re-evaluates priorities based on deadlines and progress
- User reviews suggested changes and confirms or adjusts
- Updated task list is displayed
Productivity Analysis:
- User navigates to analytics section
- System generates reports on task completion rates and efficiency
- User explores insights and adjusts work habits accordingly

Deployment Strategy

Use containerization with Docker for consistent environments
Deploy backend to cloud provider (e.g., AWS Elastic Beanstalk)
Host frontend on CDN (e.g., Cloudfront) for fast global access
Utilize managed MongoDB service (e.g., MongoDB Atlas)
Implement blue-green deployment for zero-downtime updates
Set up automated backups and disaster recovery procedures
Use logging and monitoring tools (e.g., ELK stack, Prometheus)
Implement rate limiting and DDoS protection

Design Rationale

Chose React for its component-based architecture, which allows for reusable UI elements and efficient updates.
Selected Node.js to maintain a JavaScript ecosystem across frontend and backend, simplifying development and allowing code sharing.
Opted for MongoDB due to its flexibility in handling varying task structures and easy scalability.
Integrated AI suggestions to provide unique value and differentiate from standard task managers.
Prioritized a clean, intuitive interface to reduce cognitive load for users managing complex task lists.
Emphasized analytics to provide actionable insights and encourage continuous improvement in productivity.
