During October 2025, Yujin Jeong enhanced the woowacourse-teams/2025-ah-madda repository by refining the group selection flow, renaming “group” to “position” throughout the UI to improve clarity for users. Leveraging React, TypeScript, and CSS, Yujin updated button styling and aligned the color scheme with the latest design system, ensuring visual consistency and supporting a smoother onboarding experience. The work focused on frontend development and UI/UX design, with careful attention to code quality and maintainability through well-documented commits. No major bugs were addressed during this period, as the primary emphasis was on terminology updates and design-system alignment.
