Pepe worked on enhancing the CI/CD pipeline for the 40acres/40swap repository, focusing on backend workflow stability and security. He upgraded Docker-based GitHub Actions from version 5 to 6, leveraging new features and security patches to improve reliability. To address persistent build errors, Pepe disabled multi-platform Docker builds, restricting images to linux/amd64, which stabilized the pipeline and reduced flaky builds. His work primarily involved editing YAML configuration files and integrating Docker with GitHub Actions, resulting in faster feedback loops for developers. Over the month, Pepe delivered targeted improvements that increased maintainability and security in the project’s automated build process.
