Leo designs products that feel obvious the first time you use them

I’m a product designer who works across research, interface and the build. I join small teams early, find the simplest version of the idea, and stay until it ships and people actually use it.

Site of the Day

Picked by the Design Index jury for the Crowdsurf launch site and its ticketing flow.

Leo took an onboarding flow nobody wanted to touch and made it feel obvious. Activation went up the month we shipped, and our engineers loved his handoff.
