Designing the moment before decision.

I'm a product designer who builds in code. I bring design craft and engineering judgment to AI-native and enterprise products.

I design and build with AI

About

Portrait of Christy Yao.

Hi, I'm Christy.Product designer in New York.

I started in electrical engineering, where I learned that every system is a set of decisions someone else has to live with. I found I cared more about the someone else than the system, which pulled me toward design and through a Master of Product Innovation at Carnegie Mellon.

Today I design AI-native and enterprise products, and I build in code, including this site, so ideas get tested where they will actually live. That work now includes AI in the loop: it drafts fast, so my job is deciding which draft is right, and which one only sounds right.

When I'm not designing, I spend a lot of time in museums and trying new tools. I'm mostly looking for the same thing in both.

How I Work

I design like an engineer.

I was an engineer first, so I know where designs break.

It's rarely in the mockup.

Decide

I design the decision, not the dashboard.

Dashboards show you everything. I care about the one moment you decide.

Most of the projects I work on are about that gap.

I design in working code.

I test ideas in working code, not decks.

You are looking at one right now.
