Worked on enhancing the robustness of the folder metadata API within the Accenture/sfmc-devtools repository by addressing a bug that caused downstream errors when the Results field was null or undefined. Applied defensive programming techniques using JavaScript and TypeScript, implementing a solution that defaults the Results field to an empty array to ensure consistent API responses. Collaborated closely with backend and API teams, participating in code reviews and internal testing to validate the fix and maintain compatibility. This work improved error handling and stability in folder metadata workflows, aligning with reliability goals and supporting a smoother experience for developers integrating with the API.
