Worked on the portworx/px-backup-api repository to enhance API signaling and clarify backup readiness semantics over a two-month period. Delivered an API feature that introduced a boolean field to the BackupScheduleEnumerateResponse, allowing clients to reliably detect when backup schedule enumeration is complete, which reduced unnecessary polling and improved integration workflows. Addressed a bug by refining the isBackupReady_for_PXDLocalSnapshotRestore flag, ensuring it accurately reflects backup readiness only when all volumes are PXD and local snapshots are complete. Maintained backward compatibility throughout, leveraging Go and Protocol Buffers to update proto-generated files and stabilize backup and restore workflows for clients.
