How I work

Three habits that show up in every project.

Think

Start with the mental model

I map what people believe is happening before I decide what the interface should show.

Feel

Design for the emotional moment

Trust, doubt, and relief shape decisions as much as clarity does, so I design for them on purpose.

Behave

Measure what people do

Interviews tell me why. Usage data and tests tell me whether the design changed anything.

Experience

Where I’ve been learning.
