Have you ever counted how many times one job gets typed into something? The call gets written down. Then it goes into the schedule, then a spreadsheet, then the invoice, then an email when the customer asks how it's going. Five entries. One job. That happens every day in nearly every service business in Texas.

The re-typing is one leak. The calls that ring out while your hands are full are another. So are the "any update?" emails from your biggest accounts. None of it shows up as a line on a P&L, but it adds up to real jobs lost and real evenings gone.

Critical Systems fixes exactly that. I connect the software you already use, automate the answering and the chasing, and build the small tools nobody sells off the shelf. Fixed prices. No platform subscription. No three-year contract.

The leaks

every service business has them
LEAK_01

Missed and after-hours calls

Every unanswered ring while you're on a job is a customer dialing your competitor next. And if you advertise 24/7 service, your phone system is out there making that promise alone. Fix: a text back in under a minute, with AI intake that captures the job details.

LEAK_02

"Where are we on this?"

Commercial clients want status, constantly. Answering the same question by phone and email eats hours you should be billing. The accounts that stop getting answers quietly find a vendor who provides them. Fix: job-status updates that send themselves.

LEAK_03

Humans as the integration layer

The same job typed into the phone log, the schedule, the spreadsheet, and the invoice. People re-keying data between systems is the most expensive software a business can run. Fix: connect what you already have and enter everything once.

What I build

owned by you · no platform subscription
BUILD_A

The invisible employee

Texts back missed calls in under a minute. Captures job details, books appointments, follows up on every open quote, chases overdue invoices, asks for reviews. It works around the clock and never needs reminding.

BUILD_B

Systems that talk to each other

Phones, scheduling, spreadsheets, invoicing, and the customer list, connected. Data goes in once and flows to every place it needs to be. Your tools stay. The re-typing goes.

BUILD_C

Custom tools

Job-status feeds for commercial accounts. Customer portals, dispatch boards, field-notes-to-paperwork automation. Built to fit how your operation actually runs, not how a vendor wishes it did.

The procedure

fixed price · in writing · before work starts
StepOperationWhat you get
01 Automation audit1–2 weeks · flat fee · credited toward any build I spend time inside your workflow, then hand you a written report: where the money is leaking, what each fix costs, and what order to do them in. If there isn't enough worth fixing, the report says that too.
02 Fixed-price buildprice + timeline in writing · acceptance criteria agreed up front No hourly meter. You get the price and the timeline in writing before the deposit. The build is done when it passes the acceptance criteria we set up front. If it doesn't do what the paper says, you don't owe the balance.
03 Managed automationflat monthly · month-to-month · cancel anytime Monitoring, break-fix, and steady improvements for a flat rate. Think of an IT department that costs less than a part-time hire. No multi-year contract, ever.

The operator

local · accountable · no call center

I've spent 15+ years as a senior systems engineer running enterprise infrastructure for a regulated company. Storage, networks, disaster recovery. The kind of environment where systems can't go down and data can't leak. I build automation for local businesses to that same standard, with the latest AI doing the heavy lifting.

I'm based in Rockwall and work with trades and commercial service businesses across DFW and North Texas. When you reach out, you get me. Not a sales team. Not an offshore queue.

OwnershipYou own what I build. Perpetual license. It keeps running even if we part ways.
DataStays in accounts you control. Never sold, never used to train AI models.
PricingFixed, in writing, before work starts. Changes quoted before any work begins.
SupportMonth-to-month. No lock-in, no multi-year contracts.
