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 based in Washington state. My focus is on creating digital products that are easy to use and prioritize user experience. I care deeply about ensuring that interfaces are simple to understand, as confusion can result in danger or a loss of trust.

I enjoy improving complex workflows, enhancing design systems, and collaborating with colleagues from various departments to make technology feel reliable, human, and user-friendly. When tight deadlines or other constraints lead teams to consider short-term solutions, I advocate for accessibility and clarity.
