Worked on the SMU-LikeLion-13th/LikeLion13th-FE repository to improve project maintainability and onboarding efficiency. Focused on repository hygiene by removing unnecessary macOS .DS_Store files, reducing non-functional metadata and keeping releases clean. Standardized documentation by introducing README.md files across user directories, outlining Git commit conventions and submission guidelines to ensure consistency for contributors. Emphasized collaboration and project management skills throughout the process, using Markdown to create clear, accessible documentation. These disciplined changes streamlined the onboarding process, reduced ramp-up time for new team members, and established a more reliable structure for ongoing collaboration and governance within the frontend codebase.
