During October 2025, Yujin Jeong enhanced the woowacourse-teams/2025-ah-madda repository by refactoring the selection flow to update group-related terminology to position, aligning the interface with the latest design language. Using React, TypeScript, and CSS, Yujin focused on UI/UX improvements by updating button styling and applying a new color scheme, which improved visual consistency and supported user onboarding. The work demonstrated attention to design-system alignment and code maintainability, with clear, well-documented commits that facilitate future reviews. While no major bugs were addressed, the feature work contributed to a more intuitive user experience and reduced confusion during the onboarding process.
