Worked on the ava-labs/avalanchego repository to enhance development workflows by focusing on code ownership and CI/CD automation. Updated CODEOWNERS files using YAML to assign clear responsibility for testing-related directories, which improved review efficiency and accountability across the team. Developed and integrated a CI workflow leveraging GitHub Actions and token-based authentication, enabling automated pull request comments and inline review feedback through the Claude Code Action. These changes streamlined the code review process, reduced manual effort, and strengthened traceability and governance. The work demonstrated a methodical approach to DevOps practices, emphasizing maintainability and developer productivity without introducing new bug fixes.
