Hello,
I'm Dhiego
Product Designer with 7+ years on SaaS, healthtech and B2B products, and enough front-end to build some of them myself. Most of my work is design token architecture, and turning business rules and regulated flows (identity checks, payments held until a service is done) into screens people can get through.

What they say about me.
"Dhiego's work was exceptional from research all the way to visual design. He understood the product, not just the screens, and his illustrations fit every app we built, in whatever style it needed."
- Bruno Vencato, CEO at Meaple, formerly Ensight
"Dhiego is a designer well above the curve. He delivered fast and always thought outside the box to bring the best solution to the table."
- Leonardo Volpato, Senior Designer at Instivo
