Worked on repository hygiene within the UNIkeEN/SJMCL project, focusing on improving version control practices through targeted maintenance. Addressed a specific issue in the .gitignore file by removing a duplicate entry for .DS_Store, which helped reduce unnecessary clutter and prevented accidental tracking of macOS system files. This change enhanced the overall cleanliness and auditability of the repository, supporting better collaboration and workflow efficiency. Utilized git and version control skills to implement a low-risk, easily reviewable update. The work demonstrated attention to detail in managing repository configuration, contributing to a more streamlined and maintainable development environment for the team.
