Design Rationale

The Intelligent Task Priority Learning System is designed with a focus on scalability, performance, and user experience. React was chosen for the frontend due to its component-based architecture and efficient rendering, while Node.js provides a JavaScript-based backend for consistency across the stack. PostgreSQL offers robust relational data management, essential for tracking complex user progress and course relationships.

The intelligent prioritization feature is implemented using machine learning techniques to analyze user performance and adapt the learning path dynamically. This approach ensures a personalized experience that keeps learners engaged and optimizes their learning outcomes.

The modular file structure and use of containers facilitate easier maintenance and scaling of the application. The deployment strategy leverages cloud services to ensure high availability and performance, while the CI/CD pipeline allows for rapid iterations and updates to the platform.

By focusing on responsive design and accessibility, the system ensures a seamless experience across devices and for users with diverse needs, making education more accessible to a wider audience.
