Approach
01

Identify Friction

Pinpoint where users struggle, hesitate, or drop within a journey. Not only at obvious entry and exit points.

02

Validate Direction

Use concepts, flows, and early testing to understand what improves the experience before committing to a build.

03

Refine Interaction

Design solutions that feel intuitive and lightweight, grounded in real user context rather than edge cases.

04

Apply the Learning

Carry insight from one test into the next. Small interaction changes accumulate into system-level impact over time.

About

I focus on how things
connect, scale,
and actually work

I am a senior product designer with 7 years shipping across e-commerce, mobile, and internal tools. My focus is on reducing friction, preserving context, and turning small interaction changes into meaningful product impact.

At PrettyLittleThing I owned design independently across core journeys, built and evolved the design system, and progressed from UX Designer to Design and Experimentation Manager.
