Jan ChangSenior Product Designer · Vancouver, BC

A product designer who actually likes meetings.

I enjoy conversations with project managers, researchers, engineers and stakeholders. And I design things that ship.

How I can help your team

I lead end-to-end design as a tech-literate architect, prototyper and alignment facilitator.

Code literacyTechnical UXI read HTML, CSS and JavaScript, so I design with technical constraints in mind and close the gap between UI and front end.
ArchitectureComplex information, made clearI map complex technologies and fragmented data into data visualization systems and AI interaction models.
FacilitationTeam alignmentWhen stakeholders disagree, I turn conflicting opinions into quick AI or hand-drawn prototypes the team can test right away.

About

Outside of Figma and front-end code, I’m an open-water swimmer, a plant parent and an avid picnicker.

Engineering and business degrees in Taipei, then an MS in Human Centered Design & Engineering at the University of Washington. I’m also a Toastmasters club president, so yes, I like meetings.

The open-water swimmer. I like challenges that take mental grit, like a 3,300-metre open-water marathon swim.
The plant parent. I propagate large-leaf indoor trees and grow Thai basil on my balcony.
The sun-chaser. When the sun’s out, I’m on a picnic mat at a local park, catching up with friends.

Overcoming iteration barriers in AI code generation

The problem I fell for

People felt they had lost control of the AI. They asked for one change and it changed everything.
