R. Hager enhanced the vfsfitvnm/terraform-provider-aws repository by implementing deletion protection for AWS EKS clusters, introducing an enable_deletion_protection flag configurable during creation and updates. This feature, developed using Go and Terraform, reduces the risk of accidental cluster deletions in production environments and was validated with automated acceptance tests and thorough documentation. In the shopware/docs repository, Hager updated CDN DNS configuration guidance to clarify domain pointing for Fastly CDN integration, detailing CNAME and A record requirements for custom domains. Across both projects, Hager demonstrated depth in cloud infrastructure, infrastructure as code, and technical documentation, delivering targeted, reliable solutions.
