Rockstar🎓
Top SchoolTerje Larsen is a Senior DevOps Engineer based in Stockholm with 15+ years building scalable backend systems and developer tooling, and eight years focused specifically on improving developer velocity through automation. He combines deep hands-on experience with Nix, Terraform and Kubernetes (GKE/OpenShift) with polyglot coding in Go, Python, TypeScript and Ruby, and curious exploration of languages like Elixir and Rust. At Klarna he architected a next-generation infra delivery system and mono-repo CI/CD for 100+ services; at SEB he’s led multi-tenant GKE migration and custom CRDs while modernizing developer machines with NixOS and WSL images. An active open-source contributor, he has improved usability in widely used projects like fish-shell and the nix-community home-manager, including work that touches local LLM tooling (ollama). Colleagues rely on him for pragmatic automation that reduces toil, reproducible builds, and reproducible developer environments.
