This project aimed to unify distributed point systems into a single integrated management platform, encouraging and activating users’ reward spending. Key features included an automatic payback system applied immediately during gifticon payments and smooth integrations across multiple point services, enabling a seamless user experience without complex procedures or additional authentication steps.
We also introduced an automatic lottery entry feature to go beyond simple point usage and create a gamified, interactive consumption experience. To improve accessibility, we designed user-centered UI/UX that can be used intuitively across all age groups—from digital natives to seniors—without high learning costs. In addition, we supported stable and sustainable operations by establishing structured update processes and preventive maintenance approaches to maintain long-term service quality and user satisfaction.
We built a robust UI component architecture in a hybrid app environment based on React Native and WebView, designed for scalability and reusability to deliver a consistent UI experience. Responsive UI design was applied to core screens with frequent user interactions—such as slides, tabs, and lists—to support a wide range of device resolutions and screen sizes.
We optimized rendering performance for touch gestures and screen-transition animations to deliver smooth and natural visual feedback without frame drops or delays. This ensured uninterrupted user interaction flows and consistent interaction patterns across the platform.
We implemented UI flows that enable users to use the “Ttoto Lottery” auto entry feature on a recurring basis. A real-time notification system was added so users can immediately 확인 their winning results, and a history management feature was developed to organize entry records and allow efficient review and management of past participation.
Together, these implementations significantly improved overall usability and accessibility for lottery participation within the platform.
