Hi, I’m Sergio 👋 Senior Frontend Developer specializaing in React.

I build scalable, high-performance web applications with a deep focus on Clean Architecture and Core Web Vitals.

My approach is backed by over 7 years of experience in the JavaScript ecosystem, including the last 6 years dedicated to mastering React to solve complex architectural challenges.

My Past

My journey transitioned from Cognitive Science to Clean Code. Starting with a foundation in Cognitive Psychology (Universitat Rovira i Virgili), I cultivated strong analytical skills and a deep understanding of human logic. This background proved crucial when navigating the world of technology.

Over the last 3 years, I’ve specialized in designing, migrating, and building robust platforms from scratch. Whether I’m architecting a new product or optimizing legacy systems, my goal is always the same: translating complex requirements into elegant, scalable software that delivers measurable impact.
