Pranjal Bhatnagar upgraded the CI/CD workflow environment for the govuk-one-login/mobile-android-one-login-app repository, focusing on modernizing the build process by transitioning the GitHub Actions runner to Ubuntu 22.04. This change improved the stability and reproducibility of Android release builds, reducing environment drift and minimizing build failures. Pranjal utilized YAML to define the new workflow and leveraged CI/CD best practices to ensure compatibility with current tooling. The work addressed the need for a secure, up-to-date build environment, enhancing deployment readiness. Over the month, Pranjal demonstrated depth in CI/CD automation and GitHub Actions, delivering a targeted, maintainable infrastructure upgrade.
