About me

A little bit of my story

I’m a Brazilian frontend developer and graphic designer with over five years of experience building responsive, high-performance digital products.

My background combines Computer Science, graphic design, and hands-on experience with real-world projects. I began my professional career in web development at Jüssi and, since then, I have worked with multidisciplinary teams and major brands such as KitchenAid, Itaú, and Honda, developing accessible, responsive, and reusable interfaces.

Today, I work primarily with React and TypeScript, with a strong focus on component architecture, performance and user experience. I’m currently pursuing a master’s degree in California, expanding both my technical and product-oriented perspective.
