Taking contract builds
I take on 2–3 contract builds at a time, remote from Roanoke, VA (Eastern time).
Idea to launched iOS and/or web app, including the backend.
Assistants, summaries, agents, and Claude/MCP integrations in the product you have.
Proof: Marv and “Catch me up” on Men of Hunger. Autodemia’s model routing keeps AI spend below revenue.
A stalled, buggy, or rejected iOS app, unstuck and shipped.
Rate: $150/hr, or a fixed price per scope. How I build
Products I built end to end
Also open to remote, full-time Founding Engineer, Product Engineer, AI Engineer, or Forward Deployed Engineer roles.
How I build
AI coding agents, mostly Claude Code, do most of the typing. I own the product decisions, the architecture, and every code review.
Lint, type checks, and tests run on every pull request. If they fail, it doesn’t merge.
AI features ship with cost and quality controls: model routing, usage caps, and tests.
The same person takes it from design to the App Store, so nothing gets lost in a handoff.

Meet Marv

Marv is the AI assistant I built for Autodemia and Men of Hunger. He’s the same character in both, plain and direct, but he does a different job in each.
He gets better on his own in both. Once a day he reviews how his answers landed, from corrections, pushback, and reactions, and writes himself plain-language lessons. Nothing private makes it into them.
Latest big project Shipped
I built Rumble Studio for iOS from scratch as its sole developer, then shipped every update on iPhone and iPad. The same iPad app runs on Vision Pro, with custom UI so eye tracking can highlight each control.
2,000+ creators adopted Studio by May 2024. Some who went live with it:
More creators in the Studio case study“The Rumble Studio feature is incredible. Effortless streaming on multiple platforms at the same time.”
The personal side of building
I build with AI at work, but I also use it to solve problems at home, preserve family history, and keep track of my finances.
I’m building an AI biographer for my memoir. Custom tools connect letters, photos, stories, and interviews through a graph of people and relationships, developing the book, a wiki, and a family tree.
Letters add a voice. Connections give it context.
I use household agents with my wife, connecting Linear home tasks, calendars, and email. A morning brief helps us get going. Evening wins help us close the day.
What’s coming up. What needs attention.
I use AI to organize my income, spending, expenses, and assets into a clearer picture of my finances.
