In February 2026, Haoyang Liu contributed to the advanced-computing/course-materials repository by developing a user profile information and avatar resource. Haoyang created a new Markdown file that documents user profile details and integrates an avatar image, enhancing personal representation within the course materials. This documentation-driven feature supports consistent user identity across modules and lays groundwork for future course adoption. Haoyang’s work demonstrated proficiency in Markdown and front end development, with careful version-control practices linking features to specific commits for traceability. While the scope was focused, the contribution improved the quality and branding of the repository’s instructional content through clear, maintainable documentation.
