Worked on the icssc/peterportal-client repository to deliver a feature that enables persistent UI state for expanded and collapsed majors and minors within the course catalog. Focused on enhancing user experience by ensuring that preferences for viewing course requirements are saved and automatically restored across sessions. Utilized React and Redux for robust front end state management, implementing logic in TypeScript to initialize and persist the visibility state. The approach emphasized stable default behaviors and clear commit history, with attention to maintainability and user expectations. No bugs were reported during this period, as the primary focus remained on feature delivery and state persistence.
