Developed a manual deployment workflow for Pantheon review apps in the Lullabot/drainpipe repository, focusing on enhancing deployment governance and control. Refactored existing CI/CD pipelines using GitHub Actions and YAML to support both manual and automated deployment modes, allowing multidev environments to be deployed only when explicitly triggered by pull request labels. This approach reduced the risk of unintended deployments and improved traceability across development workflows. Leveraged PHP and YAML to integrate label-based logic, aligning deployment processes with mainline changes. The work demonstrated a methodical approach to DevOps practices, emphasizing flexibility, safety, and collaboration within version-controlled environments.
