Cristobal Graña Samanez

I'm a Peruvian-born designer and engineer with a passion for craft and enjoyability. I like to deliver products with a high level of care, and have a strong interest in solving technical problems with design.

I'm currently leading all things UX at Centauri, architecting a new design system and building interfaces that simplify the healthcare data experience with a team of designers. Previously, I was a Lead UX Engineer on the Design Foundations team at GoDaddy.
