Developed and integrated a comprehensive CI workflow for the dymensionxyz/dymension repository, focusing on automating Protobuf tooling and enforcing API compatibility standards. Leveraging GitHub Actions and Docker, the solution automated Protobuf formatting, linting, and code generation using YAML-based workflows, which improved build reliability and accelerated developer feedback. The workflow included a buf-breaking check on pull requests to proactively detect API compatibility regressions, and enforced repository cleanliness by validating the absence of uncommitted changes after Protobuf operations. This approach ensured a consistently clean working tree for all pull requests, streamlining the review process and maintaining high standards for code quality.
