🎓 CampusHive - Backend

CampusHive is a scalable and robust back-end API powering an intuitive ed-tech platform for modern learning environments. It supports course management, secure user authentication, payment integration, media handling, and more — all developed using the MERN stack and deployed on scalable cloud infrastructure.

---

🚀 Tech Stack

• Node.js – JavaScript runtime for building scalable backend services
• Express.js – Web framework for building REST APIs
• MongoDB – NoSQL database for structured and flexible data
• Mongoose – ODM to simplify MongoDB operations
• Cloudinary – Media file (image/video) storage and optimization
• JWT – Secure authentication tokens
• Bcrypt – Password hashing for enhanced security
• Razorpay – Payment integration
• Nodemailer – Email service for OTPs and password resets

---

🏗️ Backend Architecture

• ✅ Monolithic Architecture: Built using a single Node.js + Express.js application.
• ✅ RESTful APIs: All functionalities exposed through HTTP endpoints using standard methods (GET, POST, PUT, DELETE).
• ✅ MVC Pattern: Organized using Controllers, Models, Routes, and Utilities for clean separation of concerns.
