Design Rationale

The design decisions for this project prioritize scalability, performance, and user experience:

1. React and Node.js were chosen for their robust ecosystem and ability to handle real-time updates, crucial for an interactive learning platform.

2. PostgreSQL provides a reliable, scalable database solution that can handle complex queries needed for course management and user progress tracking.

3. The integration of machine learning with TensorFlow.js allows for client-side predictions, reducing server load and providing instant feedback to users.

4. The modular file structure and component-based architecture facilitate easier maintenance and future feature additions.

5. The deployment strategy using AWS services ensures high availability, scalability, and robust performance, critical for a global education platform.

6. Emphasis on personalization through ML-powered recommendations and adaptive quizzes aims to increase user engagement and course completion rates.

These decisions collectively support the goal of creating a cutting-edge, user-friendly education platform that can scale to accommodate a growing user base while providing personalized learning experiences.
