Developed and deployed an unsigned-commit policy across multiple DataDog repositories to enhance security while maintaining development velocity. In DataDog/documentation, introduced a blocking warning system in the pull request workflow that notifies authors via Slack when unsigned commits are detected, using Python scripting and YAML configuration. For DataDog/integrations-core, implemented a non-blocking alert system to inform contributors of unsigned commits without disrupting workflow. Improved CI/CD stability in DataDog/system-tests by excluding GitHub Actions commits from signature checks and updating compute_impacted_scenario.py to prevent unnecessary computations. Leveraged DevOps practices, configuration management, and Slack integration to ensure policy consistency and developer visibility.
