During a two-month period, Trto contributed to the cse110-sp25-group09/Habit-Tracker repository by enhancing the monthly calendar feature with vertical scrolling, responsive UI, and improved navigation, all implemented using JavaScript, HTML, and CSS. Trto automated JSDoc documentation generation with GitHub Actions, streamlined code formatting with Prettier, and expanded test coverage to improve maintainability. By resolving dependency and resource linking issues, Trto ensured build reliability and consistent user experience. The work also included adding documentation assets and refactoring navigation logic for better testability. These contributions reflect a focus on code quality, developer experience, and robust front-end development practices.
