Worked on repository hygiene and maintenance for the se-sac/sesac-01 project, focusing on streamlining the codebase by removing outdated assignment artifacts. The main contribution involved deleting the chest-xray-pneumonia homework directory and its nested files, which reduced clutter and minimized confusion for current and future contributors. This update was implemented through a single, well-documented Git commit, demonstrating disciplined version control practices. The work emphasized repository organization and maintainability, supporting easier onboarding for new developers. Utilized Git for source control and repository management, with attention to file structure and project scope alignment, ensuring the repository remains focused and accessible for ongoing development.
