Worked on the pressbooks/pressbooks-book repository over a two-month period, focusing on targeted bug fixes and UI consistency improvements. Addressed UI text inconsistency by normalizing contributor label capitalization in the book header, enhancing clarity for readers and contributors. Improved chapter rendering reliability by correcting chapter numbering and refining border color handling through an SCSS refactor, which separated color logic from shorthand properties for better maintainability. Upgraded the Node.js runtime to v22 to align with current platform standards. Utilized skills in frontend development, SCSS, and build tools, prioritizing code quality and maintainability without introducing new features during this period.
