Portrait of Tiffany McKee, Product Designer, smiling at the camera.

Hi, I'm Tiffany

As a product designer, I work on complicated, high-trust workflows for healthcare and nonprofit products. I make design choices based on real-world limitations, weighing accessibility, clarity, and system-level trade-offs to lower risk and speed up task completion in user flows that are sensitive.

Designing a Fantasy Sports App From the Ground Up

Developed user flows and prototypes for a fair, accessible betting experience that builds user trust.

Measurement note: Some projects were limited by nonprofit or early-stage constraints. Where full analytics were unavailable, I used usability testing, task completion without assistance, hesitation points, and confirmation clarity as proxy signals for impact.

About

I am a product designer from Washington state. I help make digital products that are easy to use and focus on people.

I really care about making things easy to understand and use, especially when confusion can lead to danger or loss of trust. I like making complicated workflows better, improving design systems, and working with people from different departments to make technology feel reliable, human, and easy to use. When deadlines or other constraints push teams toward short-term fixes, I'm okay with speaking up for accessibility and clarity.
