I build technology that moves business numbers, and AI automation that takes the manual work out of running a company.

From 2021 to 2026 I led engineering at TopHap, a real estate data company. For my last three years there I was the only person responsible for every technical decision, and the technical owner of TopHap's partnership with Realtor.com. TopHap is Realtor.com's implementation partner on Google Maps Platform, and the technology my team built powers Realtor.com's FlyAround 3D view and its dynamic map layers. Realtor.com reports FlyAround doubled mobile map engagement. In 2026, Realtor.com licensed the platform in a seven-figure source code deal.

None of the fifty-plus Realtor.com engineers on that integration reported to me. I ran multi-year initiatives across their web, iOS, Android, and backend teams anyway, and covered product, design, and analytics alongside engineering.

Along the way I built an AI delivery system: staged agents, with a human review gate at every step. Side by side with Realtor.com engineers, it took sprint-sized tasks to shipped code in a day. Twice. When an urgent third-party API bill needed attention, it produced the root-cause analysis in days, and the fix cut that spend in half. For clients, that means builds that cost less and land sooner.

Now I do this work for businesses through zCube8. For a home health agency, I scoped and built an AI referral intake system on my own, and it goes live with their intake team in October 2026. It signs into their referral portal unattended, reads every referral document, routes it to the right intake team, and puts it in front of staff. Patient data is encrypted under managed keys.

Before TopHap I was an engineering manager at Alto Pharmacy, promoted from senior engineer, and led the systems behind its expansion from one state into four new markets. Before that I spent seven years building consumer travel products at goSeek and DealBase. The experiment platform I architected there ran 90+ tests, and one of them, a new partner-selection algorithm, doubled revenue per click. I also launched a paid subscription product and moved a site with ~2M monthly visitors off its legacy platform without losing traffic or revenue.

Fourteen years shipping production code, six managing teams. I still write the code, and I still get the call when it breaks.

Why work with me

I tie technology to revenue.

A partner algorithm that doubled revenue per click. A 3D map feature that doubled mobile map engagement at Realtor.com. A platform licensed for seven figures. I measure what matters to the business, not just what shipped.

I automate the work your team shouldn't be doing by hand.

The referral intake system I built for a home health agency signs into their portal, reads each referral, and routes it without anyone touching it. I find the manual, error-prone steps in your operation and turn them into software that runs itself, with people reviewing the decisions that matter.

I still ship, and I stay.

You get a working system in production, not a strategy deck. I scope it, build it, and keep it running.

I've earned authority inside someone else's company.

Fifty-plus Realtor.com engineers, none reporting to me, multi-year initiatives across five teams. That's what embedding with your team looks like.

My numbers are honest.

When I say sprint-sized work in a day, I'll also tell you it happened twice. You'll always know what was measured and how.
