Yunseo focused on front end development for the skkuding/codedang repository, dedicating the month to refining the Contest List view’s user interface. By translating detailed design specifications into code, Yunseo adjusted layout spacing and vertically centered registered icons, ensuring pixel-perfect alignment and consistency across the page. This work involved careful manipulation of React components using both JavaScript and TypeScript, with an emphasis on maintaining design system fidelity while minimizing risk to existing functionality. Although the period did not include new feature development, Yunseo’s targeted bug fix improved UI polish and stability, demonstrating attention to detail and a methodical approach to front end quality.
