Arnaud Pasquelin refined code ownership governance for the AmadeusITGroup/otter repository by updating CODEOWNERS rules within the intellij-extension folder. He excluded build.gradle.kts from default reviewers, aligning review responsibilities with actual contributors and reducing unnecessary review notifications. This change, implemented through a targeted commit, leveraged his skills in configuration management, DevOps, and Kotlin, particularly with the Gradle Kotlin DSL. The update improved repository maintainability and accelerated pull request approvals for IntelliJ extension changes. While the work focused on a single feature and did not involve bug fixes, it demonstrated thoughtful repository stewardship and a clear understanding of collaborative development workflows.
