MILLERTECK.

La Grange, Texas

I keep the systems running, and build what's missing.

I'm Christopher Miller, the IT coordinator at McCourt Equipment. I look after the networks, cameras, servers and Microsoft environment across our Texas locations. Along the way I've built around two dozen tools the business needed and didn't have — most of them still in daily use. I build those with AI tools rather than by hand, which I explain on the about page.

Dead Reckoning — answers from the equipment manuals

Our technicians need specs and diagrams out of thousands of PDF manuals, and finding them meant calling one of the two people who knew where to look. This lets them ask a question and get an answer that shows the exact manual page it came from, with that page on screen next to it. If the manual doesn't cover it, it says so rather than guessing — which mattered a lot, because a wrong torque spec on a rock crusher is a safety problem, not an inconvenience.

AggFlow Reader — screen sizing without the handbook math

Sizing a vibrating screen for a customer means working through a page of handbook calculations by hand. Two people here could do it reliably, so everyone else waited on them. This reads the customer's plant design file, does the math, suggests the right screen media, and produces a finished report. It went through five versions as people told me what they actually needed.

VaultLine — a replacement for our document system

Invoices reached us four different ways and got filed by hand, and the commercial product we'd otherwise pay for is expensive per seat. This takes documents in from all four routes, reads scanned ones, pulls out the details for a person to confirm, and files them somewhere searchable with a record of who did what. It's the largest thing I've put together and the one I'd most want to talk through.

What I work on

Day to day

Networks and infrastructure

Ubiquiti UniFi across our locations — routing, switching, access points, cameras and door access. Network segmentation, site-to-site VPN, firewall rules and wireless coverage. Starlink for sites and situations where normal connectivity isn't an option.

Microsoft 365 and identity

Our whole Microsoft environment: accounts and access in Entra ID and Active Directory, SharePoint structure and the company intranet, Power Automate workflows, and automated reporting that reads from mailboxes on a schedule.

Systems that touch hardware

The things that aren't quite IT and aren't quite anything else: gate controls wired to relay hardware, a lightning monitor that sets off the yard alarm to get people to safety, camera integrations, and timeclock kiosks across nine locations.

Tools for the business

Whatever's missing. A quote converter, a service ticket pipeline, fleet reporting, asset tracking, document handling. Usually it starts with somebody spending hours on something that shouldn't take hours.


Looking at what's next

I'm interested in IT, infrastructure and internal tooling roles. Happy to talk through any of this in more detail.
