Asier Ugarteche migrated the CI/CD pipeline for the Financial-Times/n-syndication repository from Heroku to AWS, establishing a more reliable and repeatable deployment process. He standardized the CI workflow and executor usage, updating the dotcom-tool-kit orb and simplifying configuration by removing unnecessary matrix parameters. Using YAML and leveraging DevOps and configuration management skills, Asier introduced tag-based gating for builds, tests, and publish steps, ensuring that only version-tagged releases are deployed. This approach improved release control and reduced risk by preventing accidental publishes. His work laid the groundwork for scalable cloud deployments and safer, auditable release processes within the project.
