Top SchoolSune Keller is a Chief IT Software Architect based in Copenhagen with 11 years of experience designing cloud-native platforms and enterprise-grade DevOps solutions. He holds an MSc in Digital Media Technologies and has led large transitions to major cloud vendors while building Docker-based CI/CD platforms for both greenfield and legacy systems. Hands-on in back-end and cloud infrastructure, he contributes to high-profile open-source projects such as HashiCorp’s Azure Terraform provider, Docker’s swarmkit, and the Terraform GitLab provider, often adding security- and orchestration-focused features. His work spans secrets management, managed WAF rules, and GitLab API enhancements, reflecting deep expertise in infrastructure-as-code, container orchestration, and secure cloud configuration. Colleagues rely on him for pragmatic architecture that balances automation, compliance, and developer productivity. An often-overlooked strength is his blend of academic rigor and practical tooling experience—he’s a self-described “Docker Captain” who still writes production Go and Terraform code.
