What I'm looking for

I'm looking for a collaborative environment that values quality and innovation.

I'm a frontend developer with over 8 years of experience, specializing in high-traffic platforms. My expertise lies in modern technologies such as React, Next.js, and TypeScript. I prioritize performance, accessibility, and quality in my work, and I am committed to team collaboration. I apply Clean Code principles, modular architecture, and automated testing to ensure the highest standards in my projects.

Currently, I serve as a Senior Frontend Engineer at Adevinta Spain, where I work on products like Milanuncios, InfoJobs, and Fotocasa. My role involves implementing SSR/SSG, improving Core Web Vitals, and utilizing design systems and internal tools. Previously, I have contributed to various banking clients at GFT Spain and have experience in telecom platforms and full-stack development.

I believe in fostering a team spirit, sharing knowledge, and engaging in respectful code reviews. I enjoy mentoring junior teammates and am passionate about building meaningful products that make a difference.
