Kostola enhanced governance in the Azure/ARO-HCP repository by updating the CODEOWNERS file to include themselves across frontend, backend, and internal directories. Using YAML and applying DevOps best practices, Kostola’s change clarified code review responsibilities and streamlined the assignment of ownership, directly addressing review bottlenecks and improving approval speed. The update ensures that code review coverage is comprehensive and that accountability is clearly distributed among team members. While the work focused on a single feature and did not involve bug fixes, it demonstrated a methodical approach to codebase stewardship and process improvement, emphasizing maintainability and collaborative development within the team.
