The build record · Detroit · Since 2015

From prototype
to production.

Fourteen ventures built end to end since 2015, eleven live right now. This page is the whole record.

Fourteen ventures below. Eleven are up right now, one is parked and two are retired. Two are on the App Store. More have been built and retired over the last decade, these are the current ones. I pay the inference bills on all of it, which is where I learned how cost, latency and quality actually trade against each other in production.

The build record

Fourteen ventures. Eleven of them are up right now.

Every one went from first commit to live URL without a team. Two shipped to the App Store. One is the agent that runs the rest. Every tile says where it stands.

Honest range

What I build, what I don't, and why a buyer should care.

The first two lists are short and checkable on purpose. The third is the only reason the first two are on this page.

WHAT I BUILD
  • Production apps on frontier model APIs
  • Agentic workflows that run unattended
  • Native iOS, shipped to the App Store
  • Full-stack web, front end to database
  • Payments, subscriptions and billing
  • Transactional and lifecycle email
  • Edge deploys and infrastructure
  • Brand and visual design
NOT GREAT AT
  • Model research. I build on frontier models, I do not train them.
  • Native Android.
  • Managing a team. Everything on this page shipped solo.
WHAT SHIPPING BUYS

Having shipped it is the only thing that makes the answers real.

  • When someone asks how streaming, retries or context limits behave under load, I answer from having shipped it.
  • I know what an integration costs to run, because I pay for mine every month.
  • I can usually tell a demo from a production system in one question.
  • Knowing when an answer is harder than it sounds matters more than writing every line of it.

Here's to the crazy ones. The misfits. The rebels. The troublemakers. ... Because the people who are crazy enough to think they can change the world, are the ones who do.
