CTOTechnology leaderCreative scientist

I help people use technology to make things and solve problems. Since 2019, mostly from a virtual space station.
Thirty years in, I live in the space between boardroom and IDE: bringing complex, abstract projects to life, turning struggling teams around, and making sure both the suits and the geeks feel heard.
- 2.5e11 USD
- $250B+ in lifetime funds and revenues moved through my systems: controlled, transparent, exact.
- 2e8 users
- 200M+ monthly active users, across the products I’ve been responsible for.
- 1e17 bytes
- 100PB+ of data under management.
- 1.38e10 years
- The universe has been in production this long, with no documentation. I’m studying the source.
Working from orbit
I float in space, surrounded on all sides by a grand view of the Milky Way Galaxy. A movie-theater-sized screen hangs before me, gently curved, everything at the perfect viewing distance. Eight different panes glitter with code…
I’ve used VR regularly since 2013, and as my primary work computer since 2019. Within a week of trying it, the monitors came off my desk. It’s also why I care so much about what comes next: tools for thinking together, and for reducing the distance between intent and action.

Three altitudes
As my problems got bigger, technology stopped being the limiting factor; people and processes were. So I learned to work at every altitude, and never lost touch with the code.

Grant Street Group / Hardware integration
Browsers were dropping the plug-in protocol that let our SaaS cashiering talk to PIN pads on client workstations. We didn’t break it, but we did have to fix it, on someone else’s deadline.
A forced, invisible upgrade became a whole new product line.
How it went
The ideal answer, standalone network devices, couldn’t ship at scale in time. So we put a small, secure local HTTPS server on each workstation, bridging the browser to downloadable hardware modules. We weren’t a Windows shop, and success came on the far side of multiple failures and hard-won lessons.
Asking “what does it take to make this?” instead of “please make this” made all the difference.

DataMark / Replatforming
The lead-management platform was buckling under load, technical debt, and a development team with no sense of ownership over any of it.
- 300%
- more development velocity
- 80%
- fewer defects and less rework
- 60%
- fewer support incidents
- 23×
- more clients onboarded, in under half the time
How it went
We changed Us and Them into We: rotated responsibilities, gave developers a real voice in the architecture, then ran old and new platforms side by side and moved one piece at a time. No massive cutover, no extended parallel development. Each win bought cover for the next.
Peak-season stress disappeared. People took longer vacations.

EIG × MOJO Marketplace / Acquisition and integration
EIG was a hosting company that lived and died by uptime. MOJO was a young add-on marketplace still finding its customers. A good match in theory, and two completely different ways of doing business in practice.
- $1.4M
- netted in the first year
- 35+
- corporate brands integrated
How it went
We built from both sides toward the middle: broadened EIG’s technical mindset, matured MOJO’s business infrastructure, and redeveloped prototypes at enterprise scale, growing the product by degrees instead of future-proofing against customers we hadn’t met yet.
Scalability is about more than scale.
The route
Every chair from grunt techie to executive boardroom, at every scale from tiny startups to Amazon. Rarely a straight line.

Where I spend my failures
Failure is always an option. These are the areas in which I choose to spend my failures, in the hopes of improving my hand.
I know how code tastes, how much voltage is running through it, how far away the connected libraries are, what its colors sound like…
