About Me

As a senior frontend developer, my approach goes beyond writing functional code. I'm passionate about creating exceptional user experiences that are intuitive, accessible, and visually appealing.

My experience ranges from architecting scalable applications to implementing pixel-perfect designs. I've led migrations from monolithic architectures to microfrontend, established WCAG 2.2 accessibility standards in enterprise products, and developed design systems used by entire teams.

I'm currently expanding my knowledge in UX Design with Google, because I firmly believe that the best products are born when we combine technical excellence with a deep understanding of the user.

Outside of code, I maintain an active balance with Latin dance (salsa and bachata), which has taught me about discipline, teamwork, and the importance of constant practice—skills I apply directly to my professional development.
