Andrew Chu focused on backend development for the uw-datasci/uwdsc-website-v2 repository, addressing a targeted issue in the admin user management API. He enhanced the GetAllUsers endpoint by including the isMathSocMember and eventList fields in its response, resolving a data omission that previously limited admin reporting and user experience. Working primarily with TypeScript and leveraging his API development skills, Andrew delivered the fix as a single, well-documented commit, ensuring clarity in the project’s history. The update aligned backend data contracts with frontend expectations and was prepared for QA validation, demonstrating careful attention to data completeness and maintainability.
