Worked on backend development for the AztecProtocol/aztec-packages repository, focusing on stabilizing transaction proving results within the TX pipeline. Addressed a schema validation issue by correcting a typo in the TxProvingResult schema that previously referenced ProvingTimingsSchema incorrectly. This targeted fix, implemented in TypeScript using Zod for schema validation, eliminated persistent parsing errors from PXE.proveTx and improved the reliability of transaction proving result processing. The work demonstrated careful debugging and a methodical approach to backend maintenance, ensuring more robust handling of transaction data and reducing downstream failures in the protocol’s proving flow during the development period.
