Angel Ragas developed and refined a markdown-based profile feature for the advanced-computing/course-materials repository, focusing on clear documentation and repository hygiene. Using Markdown, Angel created a detailed profile including personal and contact information, an image, and unique personal interests, then iteratively improved the content for clarity and accuracy. The work included cleaning up macOS DS_Store artifacts to ensure cross-platform repository cleanliness and easier version control. By addressing both content polish and artifact removal, Angel enhanced documentation quality and traceability for the team. The project demonstrated attention to detail in documentation and repository management, contributing to a more maintainable codebase.
