The Business-Down Method™

Engineering decisions,
derived down from the P&L.

Most technology advice starts with the technology. Mine starts with the business — where you make money, where you lose it, what the board is actually asking — and derives the architecture, the team, and the AI down from there. It's the same method every time. The answer never is.

The method is how I engage: disciplined, repeatable, accountable. What I build inside it is never boilerplate — in the AI-native world the state of the art moves too fast for canned solutions. The spine stays; the solution is always current.

Read → Direct → Build → Operate.

Four movements, one spine. Each call derived down from the business — never off a shelf.

01 · Read · Weeks 1–3

Diagnose the system and the business

A clear-eyed read on product, team, architecture, security and spend — tied to your P&L. The real root cause, not the loudest symptom, plus where AI creates measurable leverage and where it's a distraction. You leave with a 90-day plan you can act on immediately, with or without me. Available as a fixed-fee engagement — see pricing.

02 · Direct · Weeks 3–6

Set the AI-native direction

Technology strategy tied to revenue. An architecture that scales. An AI-native operating model and the org to run it. Build-vs-buy, security and compliance posture, and the hiring plan — every call derived down from the business.

  • A roadmap
  • An architecture blueprint
  • An org & hiring plan
  • An AI governance & usage policy

Ship the systems, build the team

Hands-on. Production AI systems in the product and the pipeline — agentic and retrieval architectures with the right guardrails, eval, observability and cost control built in. The SDLC rebuilt AI-first, security in every pull request. And the AI-native team, hired and operating, delivering at elite DORA. This is the part most "AI advisors" don't do. I do.

Run it, measure it, make it stick

AI moves too fast to rest on a launch, so the work compounds. I run the operating model and measure it — DORA for delivery, cost and quality for AI systems — re-run evals as models drift, adopt what's genuinely better, and feed production signals back into the product. Then I plan the transition: to an internal hire, an advisory cadence, or a trained team. No permanent dependency.
