Worked on the Code-4-Community/c4c-ops repository, focusing on backend and frontend reliability improvements rather than new feature development. Addressed a critical authentication issue by adding a Content-Type header to backend POST requests, which resolved token exchange failures and improved API integration. On the frontend, simplified the application table component by removing unnecessary rendering checks, reducing conditional complexity and enhancing maintainability. Additionally, removed the StrictMode wrapper to streamline rendering and prevent double rendering in production builds. Utilized JavaScript and TypeScript throughout the process, applying skills in backend and frontend development to deliver a more robust and efficient user experience.
