Hi, I'm Devin.
I co-founded Robinhood Roofing in Utah and built every app it runs on: sales, claims, production, payroll, a rep app with its own battle pass, and AI agents that pick up the phone. On the side I make indie games. I find what is actually broken, build the fix, and stay until people use it.
How I work
1 / Find
I sit with reps, claims and production and map where work falls through the cracks before I write anything.
2 / Build
TypeScript, Next.js, Postgres, SwiftUI and AI agents. Small releases, straight from field feedback, usually the same week.
3 / Adopt
Hands-on training, every user migrated, and numbers that prove it: margin per job, cash forecasts, rep scorecards.
Featured build
Knocking doors is a grind where the reward comes days later, if it comes at all. I borrowed the loop that keeps people playing games and put it on the home screen of our rep app.
Reward the effort, not only the close
Every 50 doors moves a rep one spot down this week's road, so a new rep makes progress on day one. A signed deal jumps a spot on top of that.
Reset every Monday
Everyone starts even each week. A slow week ends; it doesn't follow you.
Make it real in the room
Each spot is a Plinko chip at the Monday meeting. Spot 2 unlocks Bird Plinko and spot 4 Dog Plinko, and the app keeps a running count.
One set of rules
The rep's card and the manager's tracker run the same math from the same pins, so nobody argues about the count.
Give it a face
Robin Hood walks the road in 3D. He's the archer at the top of this page.
Try it: this week's road
Sample numbers. Same rules as the app.
Last spot earned by a signed deal.
It sits next to the rest of the game layer I built for the team: a live board on the office TV that throws a full-screen alert when a contract lands, monthly scorecards, and six-week sales bursts with a leaderboard.
All running at Robinhood today. The internal tools hold customer data, so they aren't public, but I'm happy to walk through any of them.

On the side
One game idea, built three times on three stacks: a 2D web game, a 3D browser game, and a native iPhone app, plus the characters to fill them.
3D, browser, multiplayer
A first-person party game with tactical teddy bears. Friends join with a five-letter code over peer-to-peer connections, with proximity voice. I wrote the netcode: snapshot interpolation, a synced host clock and lag compensation, tested to land every hit at 150 ms of lag.
Art direction: the nightmare side is built from voxels, the teddy side is round and soft. The spider on this page is one of them.
Play itNative iPhone, Game Center
The same game rules rebuilt as a fully native Swift and RealityKit app, with custom toon shaders, outlines and fog, Game Center multiplayer, and bots to fill a lobby. In TestFlight now.
The wizards and the ghost on this page came from my Blender pipeline: procedural models, a 12-bone rig and six animation clips per character.
2D, web and iOS
Where it started: a top-down party game with an authoritative server, bots, twin-stick touch controls for phones, and a profanity filter on names and chat. Submitted to the App Store as a paid app.
