This project is an end-to-end coupon system development initiative created to drive in-store visits by delivering multiple coupon features and a user-friendly redemption experience that anyone can use easily.

The client required a system capable of operating multiple coupon types—such as discounts, free giveaways, and limited-time offers—and needed flexible admin controls to configure coupon categories and benefit details based on evolving marketing strategies.

In addition, the project demanded an intuitive user interface that enables users to check coupon details without complex steps, along with optimized accessibility in mobile environments so users across different age groups and technical skill levels can use the service comfortably.

To meet these requirements, we implemented a full coupon issuance and redemption flow, built coupon management features within an admin page, and delivered responsive web optimization—completing an O2O coupon service designed for both store operators and visitors.
