Worked on repository hygiene and maintenance for the formulaslug/fs-3-intro-projects repository, specifically targeting the KiCad Workshop LED Demo project. Focused on managing macOS-specific artifacts by updating the .DS_Store file to match the latest folder structure and attributes, which reduced unnecessary metadata in version control. This effort improved the onboarding experience and maintainability for future contributors by ensuring a clean, reproducible project baseline. Utilized Git for version control and applied best practices in collaborative software maintenance. The work addressed a single bug related to metadata noise, emphasizing attention to detail and a methodical approach to non-functional project upkeep.
