Operator profile

I build infrastructure that runs quiet, fast, and inevitable.

Solutions Architect at phData, running enterprise managed services on AWS. Before that, four and a half years at Argo Cloud Solutions: 20+ cloud migrations, landing zones, production EKS for banking and insurance.

  1. Observable by default. If you can't see it, you can't fix it.
  2. Automate the fear away. Infrastructure is code, deploys are boring.
  3. AI belongs in operations. Not demos. Agents that make real decisions with real money on the line.
