Full Stack Project
Smart Learning Management System
Project Overview
A comprehensive, full-stack Learning Management System built with the MERN stack, designed to deliver an exceptional educational experience for students, instructors, and administrators. The platform features advanced AI integration, secure payment processing, real-time progress tracking, and a modern, responsive user interface that adapts seamlessly across all devices.
Key Features & Technical Highlights
AI-Powered Learning Assistant
Integrated Gemini AI API to provide intelligent, context-aware assistance to students. The AI chatbot helps answer course-related questions, provides explanations, and offers personalized learning recommendations in real-time.
Secure Payment Processing
Implemented Stripe integration for seamless, PCI-compliant payment processing. Supports course enrollment payments with automatic invoice generation and email confirmations, ensuring a smooth checkout experience.
Hybrid Document Architecture
Designed a sophisticated MongoDB schema using deeply nested sub-documents for course curriculum (Course → Modules → Lessons) enabling atomic updates and high-performance single-query retrieval of entire course structures while maintaining data integrity.
Advanced Authentication System
Implemented dual-token JWT authentication with automatic token refresh, Google OAuth integration, and role-based access control (Student, Instructor, Admin). Features secure password hashing with bcryptjs and httpOnly cookies for enhanced security.
Real-Time Progress Tracking
Built a comprehensive progress tracking system that monitors student completion rates, quiz scores, and learning milestones. Automated calculations update course progress in real-time using Mongoose pre-save middleware.
Fully Responsive Design
Crafted a modern, mobile-first UI using TailwindCSS with custom breakpoints and utility classes. The interface adapts seamlessly across all devices (mobile, tablet, desktop) with optimized layouts and touch-friendly interactions.
Automated Email Notifications
Integrated Nodemailer for transactional emails including welcome messages, enrollment confirmations, payment receipts, course completion certificates, and custom notifications. Uses template-based email generation for consistent branding.
Dynamic PDF Generation
Implemented PDFKit for generating professional certificates, progress reports, and invoices. Documents are dynamically created from user data and can be downloaded or emailed directly to students.
Type-Safe Development
Full TypeScript implementation across both frontend and backend ensures type safety, improved developer experience, and early error detection. Features comprehensive interface definitions, type guards, and runtime validation with Zod.
Centralized State Management
Utilized Redux Toolkit for predictable state management with optimized re-renders. Implemented async thunks for API calls, normalized state shape, and custom hooks for type-safe state access across the application.
