Refactor Go services that rely on gogoproto-generated behavior (e.g., JSON serialization, custom options, field behavior).
Coordinate with the Filesystem team to validate changes, ensure compatibility, and integrate with ongoing development work.
Document migration steps and provide guidance for long-term maintainability.

Qualifications:

Solid experience working with Protocol Buffers in a Go/GRPC environment.
