Worked on the linkedin/venice repository to improve error handling in the Venice Controller by ensuring client-side errors return accurate 4xx HTTP status codes instead of defaulting to 500. Centralized the logic for HTTP status derivation within the ErrorType enum, which enhanced the accuracy of server metrics and improved the observability of error responses. This adjustment also enabled more precise auditing and logging by recording the correct HTTP status for each error type. Utilized Java for backend development, focusing on API design and robust error handling. The work addressed misclassification issues, aligning the controller’s behavior more closely with the intended API contract.
