Hi, I am Márcio. A product designer based in Geneva

I'm a product designer based in Geneva, Switzerland 🇨🇭, currently working on design systems at SonarSource.

With over +7 years of experience in UX/UI design, I’ve dedicated my career to creating seamless digital experiences that put users first. My expertise spans across user experience, user interface design, and a strong specialization in design systems and accessibility. I focus on building scalable, user-centered solutions that align with both business goals and user needs.

When I’m not designing, I love traveling, spending time with my wife and our two dogs, and — in what some may call a midlife crisis — trying to keep up on the football field in my 30s.
