Worked on the Real-Dev-Squad/website-backend repository to enhance API reliability by addressing error signaling for invalid task request IDs. Refactored the backend logic in JavaScript to ensure that requests for non-existent resources now return a proper 404 status code, aligning the API with RESTful standards and reducing client-side confusion. Updated both unit and integration tests to verify the new error handling behavior, thereby increasing test coverage and reliability. Focused on backend development, API development, and robust error handling, this work improved the clarity of client errors and strengthened the overall consistency of the API’s response patterns for missing resources.
