Run by one person who has done this before.
Limestone AI Labs is a deliberately small infrastructure and security practice, run remote-first out of Fort Worth. One operator, fixed-fee outcomes, and a paper trail you can hand to anyone who asks.

Fifteen-plus years designing, building, and running infrastructure end to end — identity and SSO, switching and firewalls, server and storage clusters, Microsoft 365, and managed endpoint fleets — including an insurance-sector company with 4,900 employees across more than 200 offices. I have stood up enterprise-scale environments from the cabling and the tenant up, more than once. The pattern repeats at every scale: most of the day-to-day is unglamorous configuration nobody has time to do carefully.
Limestone is the practice I wanted to exist: that same discipline, sized to whatever you actually are — a five-person shop or a thousand-seat operation. Most people who can pass your security audit can't build the network behind it; I do both. Identity with a backbone. A network where one bad laptop is not the whole company. Evidence that holds up when an insurer or a regulator comes asking. And AI applied where it earns its keep, which is the reading and the writing, never the judgment.
I write everything down. I tell you when I am wrong. I would rather lose a deal than take one I am not the right fit for.
Three things I hold to.
- 01 Audit before you touch anything.
Every engagement starts read-only. You get a written baseline and a mapped gap report before a single setting changes. Surprises belong in the report, not in production.
- 02 Evidence over promises.
Anyone can claim a tenant is secure. The work is producing the trail that proves it: the logs, the policies, the exports an insurer or a court will actually accept.
- 03 AI is leverage, not a headcount excuse.
The reading, the drift-watching, and the reporting run on models so one operator can cover real ground. A human still scopes the work, makes the calls, and owns the result.
Email is the front door.
