Jue Park developed a crew detail page for the CodeitFESI4-Team1/Team-1-Codeit repository, implementing ID-based navigation and refactoring API calls and query hooks to enable precise data retrieval and display of crew information. Using React, Next.js, and TypeScript, Jue enhanced the frontend experience by integrating state management and updating UI components for clarity and consistency. In the mdn/translated-content repository, Jue improved CSS documentation by correcting transition property details, updating source hashes, and refining section titles. The work focused on aligning documentation with implementation, improving developer experience, and ensuring maintainable, accurate resources across both code and documentation repositories.
