Security & compliance
The fundamentals that stop real attacks, with compliance as the evidence rather than the goal.
Expertise
What I do
Seven areas I work across, usually several at once. Each page covers what I do, how I approach it and where I have done it.
Areas of expertise
Platform engineering & SRE
Kubernetes platforms, GitOps and CI/CD that let teams ship often while production stays calm.
Linux & data centre infrastructure
Colo footprints and Linux fleets, racked, provisioned, hardened and automated end to end.
Network engineering & automation
BGP, SD-WAN, firewalls and VoIP, run through NetBox and automated with Go, Python and Ansible.
AI & LLM infrastructure
GPU nodes, model serving, RAG and MCP integrations, run with real guardrails and observability.
Cloud & infrastructure as code
AWS and Azure environments and migrations, defined in Terraform and Ansible.
Observability & reliability
Prometheus, Grafana, OpenTelemetry and Icinga2, with alerts that mean something.
Solutions architecture & leadership
Architecture reviews, target-state designs and hands-on leadership of engineering teams.
