Hi, I'm Eduardo, a Brazilian ux designer, illustrator and graphic designer. My journey in the design world kicked off back in 2002 as a web designer. I began my career in large agencies in the south of Brazil. Since then, I've ridden the wave of the Internet's evolution, collaborating with clients big and small. Art and illustration fuel my passion. While I've been doodling since childhood, over the past 14 years, I've delved deeper into studying materials, anatomy, and various art styles. My skill set covers a wide spectrum, including graphic and ux design, illustration, planning and a bit of motion. I pride myself on guiding clients towards achieving their objectives. I have a generalist profile, I have worked in many positions in the creative industry: art director, web designer and creative planner for many years in each position which allows me to have a strategic vision and understanding of communication beyond design. Although I've worked in several areas, I've managed to deepen my knowledge of design and ux. I'm always studying, I love taking courses, learning new things or looking at trends.

My journey as a freelancer began modestly when, still in my teenage years, I decided to turn my passion for web development into an independent career. Armed only with determination, skills, and a basic computer, I dove headfirst into the digital world, exploring every opportunity the internet had to offer. Today, I work as a Web Developer, creating solutions that blend creativity with technology. I focus on web development, speed optimization, and website migrations, while also resolving PHP issues, restoring lost WordPress access, and updating outdated sites. I work across platforms such as WordPress, Laravel, Shopify, and Webflow, and provide complete support for hosting, servers, email, SEO, and Google Ads—earning consistent positive feedback from satisfied clients.
