Product Engineer · Boulder, Colorado

I build AI software that survives production.

I work across product, design, and engineering: figuring out what is worth building, then building and shipping it. Not the kind that demos well and falls apart in front of real users.

On trust

The throughline across everything I do is trust. How do you make AI-era output something a business, a search engine, and a customer can actually believe?

The company

CertREV

I built CertREV from zero to revenue in three months as the sole engineer.

A SaaS platform that certifies AI-era brand content by matching it with credentialed, domain-specific experts. Built end to end in a modern TypeScript stack.

How I work

Across product, design, and engineering, end to end.

01

Decide what is worth building

The hard part is usually figuring out what to build, not the building. I start from the product and the user, not the feature list.

02

Build it and ship it

I use AI agents to move fast and stay on the hook for every line. The goal is shipped software, not a convincing demo.

03

Hand off something that lasts

I build with large language models in mind, so the codebase never becomes a black box. Your own team and agents can read and extend it long after the engagement ends.

The production bar

It has to work when it is not a demo.

Most AI work looks great in a demo and falls apart in production. I build the other kind, hardening software to a degree that was not possible a couple of years ago.

About

Philosophy taught me to ask what's true. Engineering taught me to make it hold up.

I studied philosophy at Kenyon College, grounded in epistemology and trust. I spent my early career in marketing and operations, close to how brands actually win and keep customers, before I taught myself to engineer. The throughline never changed: how you earn belief.

That background is the root of how I work. I care less about output that looks impressive and more about output that holds up when someone checks.

Selected work

Custom, per-brand software for consumer and wellness brands.

Intellipure
+ more under wrap

Software I built from the ground up, as the sole engineer, runs in production for these and other consumer and wellness brands, including one ranked among the 100 fastest-growing companies in the US. Zero-to-one builds, fractional and project engagements, fully remote from Boulder, Colorado.

In their words
“He's fast, exacting, thoughtful, and unflappable: a rare blend of creativity and rigor. Zero ego, high standards, clean communication. Give him a complex brief and a deadline; he'll make it clearer, build the path, and follow through. I'd hire him again in a heartbeat.”
Kim Walls, Fractional CMO & CEO who managed Owen directly
“Owen consistently transformed complex ideas into clear, actionable content architecture. His briefs strike a great balance between strategic clarity and creative flexibility, making design collaboration seamless. His ability to keep multi-channel output cohesive and on-brand makes him an invaluable partner on any team.”
Sonia Acosta, Creative Director, on BEB Organic and CertREV
