Key skills #

  • Kubernetes (EKS) and OpenShift, infrastructure-as-code (Terraform) and GitOps (Flux and ArgoCD). Everything I manage is declarative, automated and documented.
  • Experience with cloud providers:
    • AWS: Most of my experience is in AWS. Primarily services around EKS and RDS, so everything related to networking (VPCs, LBs, EC2), secrets (SM and SSM), certs (ACM), IAM, etc.
    • Azure: A ~year’s experience running an AKS cluster, basic networking and some databases. Azure AD usage and SSO w/ various apps.
    • Others (Only used for short term POCs and experiments): GCP, Linode, Railway, Hetzner
  • Tooling and other applications: Backstage (setting up and running our internal Backstage dev portal), GitHub Actions, containerization tools, SonarCloud, JFrog Artifactory, a bit of Jenkins, Postgres primarily for databases
  • Decent Linux/sysadmin skill set, understanding of basic OS structures, perms, networking logic. Comfortable in a terminal.
    • Operating systems: Primarily distros based on Debian/Ubuntu/Alpine and Amazon Linux. Experimenting with various OS’ (NixOS, virtualized MacOS), networking and virtualization in my homelab.
  • General programming languages/frameworks:
    • Strong: Python (especially Django) | Terraform | Bash and shell scripts
    • Basic: Golang | HTML/CSS/JS
  • Languages: English 🇬🇧 | Finnish 🇫🇮
  • Technical writing examples:
  • Personal projects: See GitHub

With Kubernetes I have experience primarily with EKS, k3s and AKS. I prefer to manage clusters with GitOps using flux, though I am also familiar with ArgoCD. I have worked with both Istio and Cilium as service meshes, and much prefer Cilium. For interacting with clusters I’m a huge fan of K9S.

Some of the Kubernetes applications I have configured and have familiarity with are kubernetes-autoscaler, nginx-ingress, cert-manager, external-dns with Route 53 and Azure DNS, oauth2-proxy with Azure and GitHub providers, redis, loki-stack, prometheus-stack, and robusta.
