What I'm looking for

I seek senior front-end roles focused on modern React/TypeScript stacks, design systems, performance and accessibility, collaborative cross-functional teams, and opportunities to mentor and modernize legacy products.

I am a Senior Front-end Engineer with 15+ years building production React and TypeScript applications, design systems, and high-performance, accessible user experiences. I modernize legacy stacks, create Storybook-driven component libraries, improve Core Web Vitals through code splitting and measurement, and partner closely with design, product, and platform teams.

I have led platform migrations, mentored engineers, implemented observability for front-end performance, and shipped end-to-end products including a Flutter mobile app and a Next.js admin console. I bring strong testing, CI, and deployment practices, and I am fluent in Spanish.
