Work

Selected infrastructure and platform engineering work. Each entry: the problem, what I did, the outcome.

• Two-site Ceph object storage for a carrier
  2026-09-09
  Red Hat Ceph Storage 8 across two datacentres with RGW multisite replication, plus the monitoring that was missing.
• Ansible Tower to AWX, twice
  2026-08-01
  Leaving Tower over licence economics, landing on RKE2, moving again when the estate standardised on OpenShift — and why the original argument no longer holds.
• Vault Enterprise: HSM-rooted seal and DR replication
  2026-07-28
  Hardware-rooted key custody for a telco secrets platform, and why we bought disaster recovery replication but not performance replication.
• VMware → OpenShift Virtualization migration
  2026-06-16
  Migrating 2,500 VMs across 6 sites with minimal downtime.
