Tomás Stonehouse
Senior Product Designer — I make complex, high-stakes software usable.
I'm a product designer who turns tangled, high-stakes software into tools people can actually use. For the past 5, I've designed enterprise products across fintech, fraud prevention, and B2B SaaS — most recently leading the redesign of Kount's flagship fraud platform at Equifax, where the tools I design now support over a million payment decisions a day.
I care most about the fuzzy front end: framing the real problem before anyone touches a pixel, then shipping a clear solution that moves a metric the business actually watches.

A few problems I've owned end to end — from research and architecture to the screens that shipped.
