Cathy Theys developed a manual deployment workflow for Pantheon review apps in the Lullabot/drainpipe repository, focusing on improving deployment governance and control. She refactored the existing CI/CD pipeline using GitHub Actions and YAML to support both manual and automated deployment modes, introducing label-triggered deployments to ensure multidev environments are only created when explicitly requested. By gating deployments behind pull request labels, Cathy addressed the risk of unintended environment creation and enhanced traceability. Her work demonstrated a solid understanding of DevOps practices and version control integration, delivering a targeted feature that increased flexibility and predictability in the deployment process.
