Worked on enhancing the issued card endpoint response in the moovfinancial/moov-go repository, focusing on streamlining the card issuance workflow. Implemented a change so that the endpoint now returns the issued card body immediately upon a successful update, eliminating the need for an additional GetIssuedCard() call. This adjustment reduced API latency and provided clients with faster, more direct feedback on card state, simplifying integration and improving backend efficiency. The work involved targeted refactoring and clear commit traceability, utilizing Go for backend and API development, and applying REST API design principles to optimize both user experience and system performance.
