Live Demo: https://learning-hub-oowi.onrender.com/
Project Overview
LearnHub is a full-stack e-learning web application designed to provide an online learning experience where users can enroll in courses, attempt quizzes, and earn certificates. The platform supports role-based access for Admin and Students and is built with scalability, security, and performance in mind.
This project demonstrates real-world full-stack development, including authentication, REST API design, database modeling, and dynamic frontend updates using JavaScript.

Project Architecture
Frontend: Handles UI, form validation, dynamic DOM updates, and API calls.
Backend: Manages authentication, authorization, business logic, and APIs.
Database: Stores users, courses, quizzes, and certificates using a scalable schema.
The application follows a modular REST design with proper separation of concerns.
Application Workflow
User registers or logs in.
Backend validates credentials and issues a JWT token.
Token is used to access protected routes.
Admin manages courses through dashboard.
Students enroll, take quizzes, and complete courses.
Certificates are generated upon successful completion.
Frontend updates dynamically without page reloads.
Performance & Optimization
Pagination implemented to handle large datasets
MongoDB indexing for faster queries
Reduced admin content update latency from ~4s to ~1s
Optimized API responses under load
Key Learnings
