Worked on the ava-labs/avalanchego repository to enhance code ownership and review efficiency for testing-related areas. Focused on updating CODEOWNERS files using YAML to assign clear responsibility for directories such as /.github, /scripts, and /tests, this change aimed to streamline the code-review process and improve accountability within the DevOps workflow. By aligning code ownership with testing directories, the update reduced review delays and increased traceability of changes, supporting better auditability and governance. The work centered on process improvement rather than feature development or bug fixes, demonstrating a methodical approach to maintainability and collaborative development practices within the project.
