Summary
👤
Senior🎓
Top SchoolTerje Kvernes is a Head Sysadmin with over two decades of hands-on experience designing and operating large heterogeneous Unix and macOS environments, currently leading infrastructure at the University of Oslo. He combines deep systems expertise—RHEL, VMware/KVM, Docker, CFEngine, Ansible, Terraform and NetApp/Cisco stacks—with practical software craftsmanship in Python, Perl, and recent Rust work to keep research and teaching services reliable at scale. A pragmatic contributor to HPC tooling like EasyBuild and CernVM-FS, he has patched architecture-specific build issues (notably aarch64) and improved server-side monitoring and packaging for scientific workflows. Terje also brings uncommon cross-discipline strengths in large-scale AV and digital signage integration, and a track record of translating messy operational needs into maintainable APIs and automation. Colleagues rely on him for preventive design as much as rapid incident response, and his background shows a persistent taste for porting, refactoring and making whole systems that work together — not just well-crafted parts.
