Inspiration
Traditional college management systems are fragmented across multiple platforms - one for attendance, another for grades, separate systems for fee payments, and scattered communication channels. This creates inefficiency, delays, and poor user experience for students, faculty, and administrators. With over 40,000 engineering colleges in India facing this challenge, I saw an opportunity to build a unified solution that brings everything together in one platform.
What it does
LearnTrack is a comprehensive college management system that unifies all academic operations:
For Students:
- Personalized dashboard displaying attendance, grades, fees, and schedules
- Real-time notifications for grades, fees, and attendance updates
- Online fee payment with Razorpay integration and PDF receipt generation
- AI-powered chatbot for academic queries
- Mobile-responsive interface
For Faculty:
- Quick attendance marking interface
- Streamlined grade entry with automatic student notifications
- Class performance analytics
- Student feedback system
For Administrators:
- Department-wide analytics with interactive charts
- At-risk student detection
- Approval workflows for schedules
- Fee collection tracking
- Attendance and grade distribution reports
Current Deployment: Serving 960 students across 8 departments and 168 faculty members, with over 345,000 records processed.
How we built it
Frontend Architecture: Built with React 18 and Vite for fast development and optimal performance. Implemented Socket.IO client for real-time notifications, Recharts for data visualization, and Axios for API communication. The UI is fully responsive using CSS Grid and Flexbox.
Backend Architecture: Node.js and Express.js power the RESTful API with JWT-based authentication. Socket.IO server handles real-time WebSocket connections for instant notifications. MongoDB with Mongoose provides flexible data storage with optimized indexes for query performance.
Database Design: Created 8 core schemas (User, Student, Attendance, Grade, Fee, Notification, Schedule, Timetable) with proper indexing on frequently queried fields. Implemented connection pooling for scalability.
Third-Party Integrations:
- Razorpay Payment Gateway for secure online payments
- Google Gemini AI for intelligent chatbot responses
- YouTube Data API for curated study resources
Deployment: Frontend deployed on Vercel with edge network distribution. Backend hosted on Render with auto-scaling capabilities. MongoDB Atlas provides cloud database with replication.
Challenges we ran into
Real-Time Notification Scalability: Broadcasting notifications to 960+ users required careful architecture. Solved by implementing Socket.IO rooms for targeted messaging, ensuring each user only receives relevant notifications.
Dashboard Performance: Initial dashboard queries took 30+ seconds with large datasets. Optimized by adding MongoDB indexes, implementing pagination, and using aggregation pipelines. Reduced load time to under 2 seconds.
Payment Integration: Handling payment verification, partial payments, and receipt generation required careful implementation of Razorpay webhooks and proper error handling for failed transactions.
Role-Based Access Control: Managing four different user roles (Student, Staff, HOD, Principal) with distinct permissions and dashboards required robust middleware and frontend route protection.
Accomplishments that we're proud of
