About
You moved fast with AI and it worked. Customers came.
Then the same speed started breaking things: production, ops, the systems nobody fully remembers building.
Every new feature costs more than the last.
I steady what you built so it stops fighting you, then help it scale.
I have been where you are. I founded and ran a VC-backed company of my own.
Nineteen years in engineering, my own products since 2007, and I still ship with AI every day.

What I Offer
This is for you if you run an owner-led business between 7 and 8 figures, you leaned hard into AI in the last year or two, and now you cannot ship without something breaking.
Not for pre-revenue teams, and not for anyone hunting the cheapest hands.
You are buying judgment, not headcount.
AI Reality Check
Ninety minutes, together.
We find where your AI build actually stands: what is solid, what is quietly at risk, and the systems nobody fully understands anymore.
You leave with a written risk snapshot and a 90-day priority sketch, yours to keep.
It is a paid session, and it credits back in full against any engagement you start within two weeks.
Book the AI Reality CheckStabilization Audit
Two to three weeks.
A full read of your tech and product in asset-value terms, with a prioritized 90-day plan.
For owners who felt the first breakage and want the whole picture first.
Fractional CPTO
Ongoing.
I work beside you on roadmap, architecture, hiring senior engineers, and shipping cadence. Your technical counterpart, not a vendor.
Three slots, by design: owners I can sit beside, not seats to fill. Scope follows what the Reality Check finds.
Rescue Project
A bounded fix, usually four to eight weeks.
I make an AI-built system stable, documented, and explainable again, so it survives the customers already using it.
When it needs hands on the code, I bring in developers. You contract and pay them directly at transparent rates. No markup on their time.
A full-time CTO runs $250,000 to $400,000 a year and takes months to hire.
How it works
-
Book the AI Reality Check. A few questions first, so we both know it is a fit. Ninety minutes, we find where your build actually stands.
-
You leave with a written risk snapshot and a 90-day priority sketch, yours to keep either way.
-
We pick the path together: audit, retainer, or rescue. The session credits in full.
If a Reality Check tells you that you do not need me yet, I will say so.

In practice
A software agency was shipping AI-written code to their WordPress clients faster than anyone could safely review it. Every gap that slipped through landed on the owner.
I built them a review layer: several models and personas reading each change from different angles, catching blind spots and security holes before anything ships. It runs overnight, and it matched their own team's review, sometimes caught more.
The owner stopped worrying about technical risk. Delivery got faster, and the same team took on more client work.
It is never perfect. It was good enough to ship.
