Case Studies

The Challenge

• The client required a robust backend infrastructure to support a growing coupon-based marketplace involving multiple user groups, including registered users, subscribers, vendors, and administrators. The platform needed to manage real-time deal discovery, secure coupon redemption, subscription-based access, vendor onboarding, payment handling, location-based vendor search, notifications, analytics, and administrative control from a single reliable system.
• Users needed a simple way to register, subscribe, discover vendors, redeem coupons, and track their savings.
• Vendors required a secure channel to register, manage business information, submit deals, and track coupon performance.
• Admins needed centralized tools to approve vendors and coupons, manage categories, configure subscriptions, publish banners, and monitor platform activity.
• The system had to support OTP-based authentication, Google login, payment gateway integration, push notifications, map-based vendor discovery, and secure session handling.

The backend needed to be scalable, maintainable, and secure enough to support increasing user traffic, vendor participation, and coupon redemption activity.
