Worked on the DSpace/dspace-angular repository over a two-month period, focusing on both security and user interface improvements using Angular and HTML. Addressed a cross-site scripting vulnerability by implementing HTML escaping in item previews, specifically targeting abstract and date fields to enhance security without disrupting existing functionality. This change improved the safety and reliability of UI rendering, aligning with secure front end development practices. Additionally, delivered a user experience enhancement by adding a funnel icon to the search scope button, making filter options more discoverable. All changes were implemented within the established Angular component architecture, supporting maintainability and code clarity.
