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 focusing on what I do best: working with cross-functional teams to create unique frameworks that help solve problems.

IA / Navigation Refactor - Information Architecture Diagram

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

Bulk delete emails by sender

+5%
Higher revenue than control
25%
WAU use context menu
+188%
Increase in deleted messages

A quick way for users to triage emails from senders in bulk resulted in increased deleted messages and is projected to increase retention over time.

User impact

UX Strategy

Exploring a holistic tactic to provide information to users. Standalone surfaces are great for hunt and peck method, whereas other tasks may be better suited as a search flow.

About

Tessa Chung - Principal Product Designer

Hi, I'm Tessa

I'm a Principal Product Designer at Yahoo, where I focus on creating frameworks and systems that help teams solve complex design problems. My work spans information architecture, user experience strategy, and design systems.

What I do

  • •Design strategy and information architecture for complex products
  • •Create 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 exploring VR development, writing about design and technology, or experimenting with new creative tools and frameworks.

Let's work together

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