Cai Toy · Design Engineer · Lehi, Utah
Design engineer.Since 1999.Now with a fleet.
I own the interface and the system under it, from design tokens to production React, and I conduct AI agents to build it with the gates in my hands. Open to part-time and contract work, remote.
01 · Halliburton · AI Solutions Architect · since 2022
One architect.A fleet of agents.
AI produces the code. I own the experience layer, the design system, the component library and the review gates the work has to pass. That is how a data-product marketplace reached worldwide production, and how a proof of concept turned into a funded build.
- 01SpecIntent becomes an order with a verified end state
- 02BuildAgents cut code in their own worktrees
- 03JudgeA different model refutes the work
- 04GateI walk it; nothing merges without me
- 05ShipIt lands where people actually use it
Tap a gem. The whole page wears its theme.
02 · Crystal · a design system since a 2018 thesis
One source.Every brand.
One token source themes a Next.js front end and WordPress alike. A theme builder ejects a whole brand from a palette. The reveals, the chapter light and the test drive on this page are Crystal parts, harvested from the showroom so every site I ship can use them.
03 · Artasce Creative · my studio since 2000
Five businesses.Five AI front desks.
- Forge Strength Strength gym

- Wick & Kiln Candles and ceramics

- Keystone Handyman Home repair

- Fenwick & Vale Tax and advisory

- Larkspur Coaching Wellness coaching

A gym, a candle shop, a handyman, a tax firm and a wellness coach. Each is a working site with an AI staffer who answers, books and quotes, built by my fleet on Crystal. Get in and drive one.
04 · Henry Schein One · 2010 to 2022
Three frameworks.Not one seam.
Twelve years holding one product’s whole visual layer together, from Backbone to Bootstrap to Bulma, so users never saw a migration. I set the accessibility standards, built the design systems the company adopted, and ran the WordPress multisite behind hundreds of dental and medical practices.
- Backbone2010
- Bootstrap2014
- Bulma2018 to 2022
- Design systems adopted company-wide: components, tokens, documentation.
- Accessibility standards (WCAG) set across product lines.
- 500+ practices on one WordPress multisite I built and ran.
Need the partpeople touchdone right?
Part-time and contract, remote from Lehi, Utah. Pick a time and I call you. Rather write? Twenty-six years in, I still answer my own email.
