During March 2025, Donguk Kim focused on improving repository hygiene and documentation for the SMU-LikeLion-13th/LikeLion13th-FE project. He removed unnecessary macOS .DS_Store files to maintain a clean codebase and prevent non-functional metadata from polluting releases. Using Markdown, Donguk standardized README files across user directories, clearly outlining Git commit conventions and submission guidelines. This work enhanced onboarding efficiency and reduced ramp-up time for new contributors. By emphasizing collaboration, documentation, and project management, Donguk’s disciplined approach improved repository maintainability and governance. The depth of his contributions lay in establishing consistent project structure and clear guidelines for future development and collaboration.
