HEY 👋 I'M TESSA

I enjoy working on ambiguous design problems—the weirder, the better.

After years of working across product design, UX/UI, graphic design, and research science, I'm focused on working with teams as a Fractional Product Designer to create unique frameworks that help solve problems.

User Action Spectrum

This Zones + Actions framework organizes our product into focused areas for specific activities. Key actions get one-click access, related actions are grouped logically, and a clear hierarchy helps users stay focused. This current assessment of our product helps us propose streamlined improvements for future IA work.

UX FrameworkHolistic concept

About Me

Tessa Chung - Principal Product Designer

Hi, I'm Tessa

My design work spans information architecture, user experience strategy, design systems, and more.

What I do

  • •Design strategy and information architecture for complex products
  • •Create holistic frameworks that help teams make better design decisions
  • •Research and validate design concepts through experimentation
  • •Mentor designers and advocate for user-centered design practices

Background

I have a diverse background spanning product design, UX/UI, graphic design, and research science. This multidisciplinary approach helps me tackle ambiguous problems from multiple angles and create holistic solutions.

When I'm not designing, you can find me tinkering with vibe coding, sketching, writing about design or music, or visiting local coffee shops in search of the best atmosphere :)

Let's work together

I'm always interested in discussing design challenges, collaboration opportunities, or just connecting with fellow designers and researchers.
