During May 2025, Rijad Kadribegovic focused on improving repository hygiene for the sozalpasan1/HWKartKlash project by updating the .gitignore file to exclude macOS system files such as .DS_Store. This change, implemented using version control best practices and Git Ignore syntax, helped prevent unnecessary platform-specific files from being tracked in the repository. By addressing this common source of noisy diffs, Rijad enabled cleaner collaboration and more efficient code reviews for the team. The work demonstrated a practical application of version control skills, though the scope was limited to a single feature and did not involve bug fixes or broader codebase changes.
