Worked on the alphagov/pay-ci repository to modernize Docker image sourcing within the CI/CD pipeline, migrating image pulls to the Amazon ECR public gallery and replacing the deprecated docker-image resource type with registry-image. This transition, implemented using YAML configuration and leveraging AWS and Docker, aimed to improve image availability and deployment speed. After rollout, a rollback was executed to restore Docker Hub sourcing, ensuring compatibility and stability across all pipelines. The work demonstrated disciplined change management, clear commit traceability, and a focus on maintaining reliable builds, while showcasing proficiency in DevOps practices and CI/CD modernization using industry-standard tools.
