Breno Guerra
UI/UX Designer, Brazil
By day, a product designer chasing the small details that make an interface feel effortless. A designer at heart, I enjoy shipping highly polished, obsessively detailed products.
Right now I'm a Senior Designer at JStack↗, shaping the product and its design system end to end. Before that, I was the Founding Designer at Tunni — building the product from zero-to-one — and spent time at Bilhon.
