Worked on enhancing the GCS User Interface by focusing on the stability and user experience of Mission and Zone Cards editing. In the ngcp-project/gcs-user-interface repository, implemented conditional rendering for editable elements and introduced robust null checks to prevent errors when accessing mission and stage data. This approach ensured that editing options appeared only when appropriate, reducing confusion and preventing invalid edit attempts. Leveraged frontend development skills with TypeScript and Vue.js to improve data integrity and minimize runtime errors during the editing process. The work emphasized careful handling of user input and data safety, contributing to a more reliable editing workflow.
