During February 2026, Kyungjin worked on the TanStack/query repository, focusing on enhancing the project’s documentation and branding through UI design and Markdown. Kyungjin delivered a theme-aware update to the README, introducing partner logos that render correctly in both dark and light modes. This approach addressed visual consistency issues and improved the onboarding experience by aligning with established branding guidelines. The work involved careful attention to cross-theme compatibility and was tracked against specific issues in the repository. While the contribution was limited to a single feature and did not involve bug fixes, it demonstrated thoughtful application of documentation and UI design skills.
