Worked on the netboxlabs/diode repository to deliver automated detection of breaking changes in Protocol Buffers, focusing on maintaining API stability during development. Developed a Makefile task that leverages the 'buf breaking' command to identify incompatible changes in proto definitions locally, enabling developers to catch issues early. Complemented this with a GitHub Actions workflow using 'buf-action' to enforce the same checks in CI/CD pipelines against the develop branch before merges. This approach improved feedback speed and governance over proto changes. The work utilized Makefile, YAML, and GitHub Actions, emphasizing build automation and continuous integration best practices throughout the process.
