About Me

I'm a Front-End Developer with a background in Product Design and a degree in Computer Science. My work focuses on turning ideas into clear, intuitive, and well-built digital products.

I believe great interfaces emerge when design and development work together. That's why I'm involved across the entire front-end pipeline, using React, Next.js, and TypeScript to create consistent, accessible, and maintainable applications.

I have experience building products for the public sector and developing my own projects, always balancing technical quality, user experience, and attention to detail.
