Worked on the XRPLF/rippled repository to enhance backend reliability by addressing error handling in the LedgerEntry::parsePermissionedDomains function. Focused on standardizing error semantics, the developer refactored C++ code to ensure that malformed inputs—such as invalid domain strings, non-object types, missing account fields, and invalid sequence numbers—produce uniform and predictable error responses. This approach aligned error handling with other parsers, improving robustness and client feedback without altering the API surface. Leveraging skills in backend development, error handling, and RPC, the work contributed to more maintainable and testable code, emphasizing reliability improvements over new feature delivery during the period.
