Founder · Applied AI Leader

I redesign service firms around how AI actually changes the work, then ship the systems.

Technical Program Manager at eBay, reporting to a VP of Engineering. My peers were directors and engineering managers. My day job was getting them to agree on trade-offs across large engineering programs. I do that job for AI portfolios now, and I ship the systems myself. Founder of baxie. Not an advisor. Not an automation shop.

The profile

Most AI help is one altitude or the other. This profile is both at once.

Setting the direction is one job. Shipping against it is another. Almost every fractional AI offer in 2026 picks one and subcontracts the other, which is exactly where the dependencies go unmapped and the work stalls. This profile carries both: program execution on large engineering organizations at eBay, named frameworks with their origins cited so your CFO can check the source, and patterns running in production today.

TPM discipline

TPM discipline, applied to AI portfolios

Technical Program Manager at eBay, reporting to a VP of Engineering, before AI was production-ready. I map AI dependencies the way I mapped engineering programs: owners, integration points, risk, downstream impact. The layer almost every AI consultant skips, because most of them have never run a program.

Named frameworks

Named frameworks, sourced and applied

Three-Horizon AI portfolio (McKinsey, 1999). Leadership-Lab-Crowd adoption (Ethan Mollick, Wharton, May 2025). Agentic pattern catalog: ReAct, tool-using, multi-step, sub-agents, self-correction. Origins cited so your CFO can quote the source and your board can audit the logic.

Production patterns

Patterns I ship in production today

Vision extraction on architectural plan sets behind a review gate enforced in the data layer. Multi-model routing tuned for cost and latency. A deterministic verifier that flags the model's outliers without overwriting them. A closed scope catalog that stops scope-name hallucination. A markup engine that throws rather than return a nonsense number. Running in baxie production.

The wedge · One sentence

Someone has to own the AI program. I worked that layer at eBay across two of its largest engineering organizations, and I ship the systems myself.

Org redesign and the build crew, from one operator. Not a deck. Not a referral.

The path

The path: eBay program execution, Mechanical Engineering, ships AI today.

Technical Program Manager on eBay's Product Strategy and Operations team, working across Core Product and Core Technology, its two largest engineering organizations. Mechanical Engineering foundation from SFSU. Builder hands that now run a production AI stack.

eBay TPM

Program execution across eBay's two largest engineering orgs

Technical Program Manager on Product Strategy and Operations. Mapped engineering program dependencies across owners, integration points, risk, downstream impact. The discipline that translates directly to AI portfolio rollouts that land.

Mech Eng foundation

Mechanical Engineering from SFSU

Bachelor's in Mechanical Engineering. Systems thinking, tolerance analysis, root-cause discipline. Same posture I bring to AI systems that have to behave in production.

Ships AI today

Production AI stack, running now

Baxie in paid beta. Three engineers' worth of work shipped by one founder on a shared knowledge base and a production AI stack. The proof is current, not historical.

How we work

What I'll bet on: engagement shapes I take.

Fractional Head of AI Transformation work. Org redesign, production AI build, workforce training, from one operator. The service ladder runs from AI Portfolio Allocation Reviews through shared-knowledge-base buildouts, scoped production builds, training, and AI System Continuity as the maintenance retainer.

AI Portfolio Allocation Review

What to fund, what to kill, what to show the board

Three-Horizon AI portfolio allocation across H1 efficiency, H2 capability, H3 transformation. What to fund this quarter, what to kill, what your board needs to see.

Shared knowledge base buildout

The layer your team and your AI both work from

AI-ready knowledge bases modeled on edwin-os. Versioned. Searchable. Both your team and your AI read from it. Sold as a scoped build, not a deck.

Scoped production build

Scoped AI builds

Vision extraction with human review gates, multi-model routing, deterministic verifiers, and prompt-injection hardening on document intake. Patterns I run in baxie production, applied to your problem.

The portfolio

Two businesses, one shared knowledge base.

Same architecture I sell to clients. The shared knowledge base is the substrate. The work compounds because the context is one layer.

Baxie

Baxie

AI-native Margin OS for residential general contractors. Paid beta. Three engineers' worth of work, shipped by one founder running off a shared knowledge base and a production AI stack.

Guzman Applied Technologies

Guzman Applied Technologies

Fractional Head of AI Transformation engagements for operators and founders. Org redesign, production AI build, workforce training, from one operator.

The rules

Four rules I won't break.

Engagements that violate these don't work. So I don't take them.

Diagnostic before retainer

I won't take a retainer from a company that hasn't tried one AI use case.

If you haven't shipped a pilot, the right work is the AI Program Diagnostic, not a 6-month retainer. The retainer pays off when there is real production behavior to redesign around. Otherwise we are designing in a vacuum.

Eat my own cooking

I won't ship a build I wouldn't run in my own production.

Every pattern I sell is one I run in Baxie today. Multi-agent orchestration, multi-model routing, vision pipelines, closed-loop learning, the shared knowledge base. If I don't run it in baxie, I won't sell it to you.

No vendor kickbacks

I won't lock you into vendors I get paid by.

Model-agnostic and tool-agnostic. I make money from your engagement. No referral fees, no reseller margins, no vendor partnerships. The stack we pick fits your work.

Team owns the work at handoff

The team owns the eval suite at handoff, or I won't ship.

Every engagement ends with your team running the eval suite, playbook, and on-call. Not a permanent dependency. If your team can't take it after handoff, the engagement isn't done.

Let's talk

If the profile fits, let's talk.

Book the call. 30 minutes. I'll tell you in the first conversation whether I'm the right operator for what you're trying to ship.
