About

I'm Cassiano, a product designer based in Florianópolis, Brazil, with sixteen years in the design field. I started my career in advertising agencies and design studios, including a four-year run with my own studio, where I learned to think strategically and became a product designer.

Moving into tech, I gained a lot of expertise across B2B and B2C SaaS platforms in many market fields, coordinating design systems, leading products shoulder-to-shoulder with product teams and C-levels, and mentoring designers along the way. Lately I've been folding AI into how I work.

Today I'm a Senior Product Designer at Siteimprove, a marketing platform, working on AI design-system components and a new content-product integration.

How I work

For me, product value comes from aligning business, technology, and usability; none of them wins alone. I stay close to the whole team, from discovery through developer handoff, because the sharpest decisions come out of that collaboration.

My process flexes to each company, but it always starts with the business context and the user's real pain, not the interface.
