I also have extensive experience with modern tooling, testing practices, monorepo structures, and frontend engineering standards that improve quality and delivery speed. A major part of my work has been accessibility and inclusive design. I have implemented WCAG-compliant interfaces, semantic HTML, responsive mobile-first layouts, and localization support, including Spanish-language experiences for critical workflows. I have also contributed as a technical leader and mentor, helping teams improve architecture, testing discipline, design system governance, and implementation consistency.
