Worked on the softwareconstruction240/softwareconstruction repository to deliver a targeted update to the course syllabus, ensuring the correct 4th edition and accurate ISBN values were reflected in course materials. Focused on content management and documentation, the update was implemented using Markdown and managed through disciplined version control practices. By correcting the edition mapping in the book list, the work improved information integrity and reduced confusion for both students and staff. The changes were consolidated into a single, traceable commit, demonstrating attention to repository hygiene and alignment between documentation and actual course requirements, ultimately supporting catalog reliability and a better student experience.
