Projects with many moving parts
Clear product
I trained as a graphic designer, studying the relationship between form and function. Over time, I realized the designs I imagined needed code to come alive. That curiosity led me to web development, and what started as a tool to bring my designs to life became a second calling.
Today I work as a full-stack developer and product designer, combining 10+ years of experience in both disciplines. I understand design from the inside and translate it into clean, efficient code. That intersection is my greatest strength: creating products that not only look good, but work exceptionally well.
I specialize in two areas: high-performance websites that combine polished visual design with technical speed, and SaaS products like dashboards, applications, and internal tools that make people's work easier. I use modern web technologies and pay special attention to accessibility, making sure what I build is usable for everyone.
I work independently from Galicia, Spain, collaborating with clients from different countries. We can communicate in Spanish 🇪🇸, Galician 🌳, English 🇬🇧, and Portuguese 🇵🇹.
I care about quality and attention to detail. I believe in doing things right: thoughtful code, intentional design, products that last. If you're looking for someone who understands both the visual and technical sides of your project, let's talk.
