// the builder model

I don't work in a circle — I work at the center.

For decades, departments existed to manage scarce specialization. AI collapsed the price of it — the constraint flipped from headcount to judgment.

So I don't hand work off between product, engineering, and design. I own the whole loop — problem to shipped — and nothing gets lost at the seams.

PRODUCTENGINEERINGDESIGNTHE BUILDER

The overlap is the whole job.

// product

Strategy, growth & GTM

I take an ambiguous idea to a prioritized roadmap for marketplace and platform products — and I've supported $110M+ in capital commitments doing it.

// engineering

AI-assisted development

Five live builds on Next.js 16, Convex, and TypeScript — written hands-on with Claude Code.

// design

Design & UX

Design systems and interfaces that make complex products feel simple.

// featured builds

Eight production builds, shipped hands-on.

Real products across real-estate, fintech, infrastructure, wellness, and creator marketplaces — designed, built, and deployed with AI-assisted development.

The builder

// about

I'm a product and marketing leader who spent 10+ years driving growth for technical marketplaces — and somewhere along the way I crossed over into building.

Today I sit at the center of product, engineering, and design: shipping production software hands-on with AI-assisted development, so I can take an idea from strategy straight through to deployed code. I'm based in Durham, NC, and I speak Mandarin.

Have a product that needs both sharp strategy and someone who can ship it? I'd love to hear about it.
