• Built a design system with 60+ reusable components for web and mobile.
• Designed unique visual styles for 40 lotteries, ensuring consistency and differentiation.
• Created new sections such as My Tickets and About Lottery to enhance user experience.
• Delivered 100+ redesigned pages, covering the full flow from discovery to purchase.
1. Create a scalable design system for web and mobile to ensure consistency and speed up future development.
2. Develop a unique visual identity for each lottery while keeping the overall brand style cohesive.
3. Improve navigation and user flows to make lottery participation clearer and more engaging.
1. The old design lacked a consistent style and design system, causing visual clutter and inefficiency in development.
2. Navigation was confusing, making it difficult for users to find tickets, understand rules, and track their participation.
3. All lotteries looked similar and undifferentiated, leading to low engagement and reduced user interest.

During the ideation stage, we ran workshops focused on information architecture and navigation, producing several alternative maps for the lottery section. We developed concepts for lottery cards and pages, each with unique visual motifs to differentiate the games and create a more engaging experience. Finally, we prioritized solutions by balancing their potential impact on key metrics with the effort required for implementation.
During the prototyping and testing phase, we created low-, mid-, and high-fidelity prototypes in Figma for both web and mobile. These prototypes included a design system with over 60 reusable components, unique visual styles for 40 lotteries, and new sections such as My Tickets and About Lottery. We conducted usability tests on key flows, iterated based on user feedback, and validated improvements through A/B testing of navigation and ticket purchase flows.
