Developed a full-stack affiliate referral system that enables customers to earn discount coupons by referring new users. The application is built using React.js for the frontend, Node.js for the backend, Firebase for authentication and real-time services, and MySQL for relational data storage.

The system tracks user referrals and automatically generates a discount coupon after every five successful referrals. Each coupon is uniquely generated, can be verified by an admin, and is restricted to single-use to prevent misuse. An administrative dashboard allows admins to manage users, review referral activity, validate coupons, and monitor overall system usage.

The application emphasizes secure authentication, role-based access control, and scalable architecture to support growing user and referral data.

• User registration and authentication using Firebase

• Referral tracking and automated coupon generation
