Worked on the folio-org/ui-inventory repository, focusing on front end development using React and JavaScript. Delivered a UI enhancement by adding a required-field asterisk to the Call Number label in the Additional Call Numbers section, clarifying mandatory input for users and improving usability. Addressed a related UI issue in the same update to ensure consistency across the interface. The implementation emphasized clean, maintainable code and adherence to UI standards, with all changes linked to relevant issue IDs for traceability. The work resulted in a ready-for-QA front end update that supports better user experience and aligns with established design guidelines.
