What I typically do, ordered by how often it’s asked:

Platform & infrastructure

  • Multi-tenant Kubernetes — setting up, running, or taking over.
  • Migrations: managed K8s to bare-metal or on-prem, and back.
  • GitOps with ArgoCD: from loose YAML to a clean app-of-apps structure.
  • Proxmox/Ceph clusters for organisations serious about sovereignty.

Compliance & ISO 27001

  • Writing controls that match your actual stack — not template copy-paste.
  • Non-conformity dossiers, RCAs, incident reports in Dutch corporate style, audit-ready.
  • Designing BIO-compatible infrastructure.

Open source & grant work

  • NLnet NGI Zero applications, written and shepherded.
  • Innovation Budget Digital Government and similar programmes.
  • Code and proposal hand in hand — no fair-weather deliverables.

How I work

By the day, by the project, or interim. Remote from North Holland, on site when needed. I always start with a conversation, then a spec, then code.
