Carol upgraded the backoffice deployment for the planetarium/9c-infra repository by updating the Kubernetes values file to reference a new application version. She accomplished this through a single, traceable commit that changed the image tag, ensuring a low-risk rollout and clear version control. Her work leveraged Kubernetes cluster configuration and Git-based deployment practices to align the backoffice with current platform standards. While the scope was focused on a single feature and did not involve bug fixes, Carol demonstrated proficiency in infrastructure automation and deployment workflows, using YAML and Git to deliver a targeted, maintainable update with minimal operational disruption.
