AI speed, seasoned judgment

I build products with AI agents, and help teams ship faster.

Anyone can vibe-code a demo now. I build the version that holds up in production. I am a seasoned engineering leader: engineering leadership across four acquired startups, founder and CTO of one. Two things. I build agentic products end to end, and I get engineering teams to AI-native development so they ship faster without giving up quality.

Engineering leadership across four acquired startups, founder and CTO of one.

01 / What I do

Where AI earns its keep.

I put AI to work in real ways: I build products with AI agents that hold up in production, and I get your engineering team building the same way, so they ship faster without giving up quality. Here is where it shows up.

01

Your own product, in weeks

What used to cost six figures and six months, now built in weeks with my team of AI agents. Your own app, platform, or AIOS, not a rented SaaS, built to hold up in production.

02

Your team, AI-native

Get your engineering team to AI-native development: spec-driven AI coding, agent-assisted pipelines, and the practices that help them ship faster while keeping quality high.

02 / Fractional leadership

When the next stage is on the horizon.

Maybe you just raised, or a competitor just landed, and you have to move now. Maybe you and a co-founder are building it yourselves. Maybe you are an engineering leader who knows a big event is coming. Maybe you are an investor about to look under the hood of a company you are backing. When the stakes are high, you want a seasoned veteran who has sat on both sides of the table. That is where I come in.

Go faster

You just raised, or a new competitor landed, and you have to move now. I help you go fast the right way: a strong system your team runs on, AI agents and engineers working together, not corners cut or builds held together with paperclips.

Cross the next chasm

Scale arrives in stages, and a new level can hit before you feel ready, whether that is the first leap from prototype to production or a wall you have not hit before. I work alongside your team to get you through it, because I have done it many times, across multiple platforms and architectures.

Diligence, both sides of the table

Getting reviewed (raising or being acquired)? I get your engineering org and your answers ready. Reviewing a target? I go through their codebase and engineering under NDA, reporting to you, before the wire goes out.

Pass an audit

HIPAA, SOC 2, or a customer's security review. I get you ready and work alongside the licensed firm.

Let's talk
03 / Why work with me

Three things that make working with me different.

01

You work with a seasoned engineering leader.

I was building production software before AI could help, and I have brought real products to market and scaled them across four acquired startups, as founder and CTO of one, from regulated healthcare to encryption products. I have probably seen something like your problem before, and what I ship holds up. I take it all the way, architect to running live, planning for what most builders skip: SLAs, backups, monitoring, incident response, the parts that break at the worst possible moment. I think before, not after.

02

I build with discipline.

Quick does not have to mean throwaway, and right does not mean over-built. I build it correctly the first time, with disciplined practices, but only as much as your stage needs, then we mature it as you grow. No AI slop you cannot make sense of later, and no gold-plated enterprise system while you are still finding product-market fit. And I direct the AI, I do not trust it. It is powerful, it is wrong a lot, and it takes the easy way out. My experience is the quality control.

03

Outcomes, not hours.

Outsourcers win the deal with a polished architect, then swap in junior engineers and bill you a rate card by the hour, a model that quietly rewards dragging it out. I work the opposite way. The person who scopes it is the person who builds it. I am selective about what I take on, and I am here to drive value and grow your business, not to bill time.

04 / Built since going independent

What I've actually built.

Real systems, running in real businesses, including my own. Apps I built solo with AI-native development, products I built with AI agents, and security diligence I have done for others. Some are under NDA. These are receipts, not opinions.

Living Design StudioLive
App, built solo with AI-native development . design and realty

A full app I designed and built solo: curation, client review, vendor follow-up, and margin-aware delivery in one place.

Problem
A design and realty business ran the whole cycle across spreadsheets and inboxes.
Built
One connected app, built solo end to end with AI-native development: product curation to client-facing review to delivery.
Status
Live, in use.
Parcel ScoutIn validation
App, built solo with AI-native development . South Florida

A decision app I built solo: tells a builder in minutes whether a parcel is worth pursuing.

Problem
A South Florida builder judged land deals on a manual spreadsheet.
Built
A decision app, built solo with AI-native development, that scores parcels fast and replaces the spreadsheet.
Status
In validation. A one-off with product legs.
Research pipelineDelivered
Product built with an AI agent team . two paid engagements

A research product I built with a team of AI agents, delivered across two paid engagements.

Problem
Two clients needed deep market and competitive research on new opportunities, done for them and curated to the decision in front of them.
Built
A team of AI agents that gather and cite sources, critique and verify each other, and curate the result to exactly what is needed. Sixteen steps, adversarial review, then rendered as a summary, a full document, or a video explainer.
Status
Two engagements, delivered and paid.
Content multiplierLive
Product built with AI agents . long-form into a week of content

An agent-based product that turns one long-form message into a week of content in many forms.

Problem
Advent Lutheran Church had one Sunday message a week and nothing structured for the days after.
Built
An agent pipeline that takes their own long-form content and reshapes it into a recap email, daily devotionals, small-group questions, and short clips. Their words, in many forms.
Status
Live for Advent Lutheran Church. Their first recap email hit a 41% open rate in 48 hours.
Music and video pipelineProducing
Product built with AI agents . original music and video

An agent-based pipeline that produces original music and video, for clients and for myself.

Problem
Producing original music and video at volume, for myself and for paying clients.
Built
An agent pipeline end to end: concept, sonic direction, production, cover art, and publishing. I have produced songs on my own and with others, and video for clients.
Status
Live. Producing for clients and for myself.
Security and HIPAA DiligenceDelivered
HIPAA diligence . recommending the way forward

HIPAA diligence I have done for multiple companies, recommending the way forward to stay compliant.

Problem
AI-built products that touch PHI, with no certainty they are HIPAA-ready or how to run them in a controlled environment.
Built
I review the product and the environment, and recommend the way forward to stay HIPAA compliant. I work alongside the licensed firm.
Status
Done for multiple companies. Built on real HIPAA and SOC 2 work.
Autonomous dev teamsRunning
How I run my own shop

Teams of AI agents that do daily software development on their own.

Problem
More to build than one set of hands can ship.
Built
Role-based agents (intake, feature, bug fix, code review) running real dev workflows behind my approval.
Status
Running on my own projects, every day.
The BrainLive
How I run my own shop

An AI operating system I run my own work and companies on.

Problem
My context as a founder lived scattered across tools, files, and memory.
Built
A plain-text knowledge system with agents that capture, organize, and act across it. I run Headmark on it every day.
Status
Live, in daily use. Proof I run the kind of system I build for others.
Not sure how to apply AI today? Let's talk Some of the best work is under NDA.

That is what I have built since going independent. See the full track record on LinkedIn.

05 / Field notes

I write about what I'm building.

Notes from the workshop: what I am building with AI agents, what worked, what broke, and what it means for the teams building alongside me. No hype, no calendar spam.
