Senior Frontend Developer
About Me
I am a principal-level frontend developer with nearly two decades of experience building and delivering production web applications. My core focus is React and Next.js, and I have deep hands-on expertise in TypeScript, modern CSS, accessibility, performance optimization, and design systems.
I have led frontend architecture for large-scale products in healthcare, SaaS, banking, and government environments. My work has supported platforms serving hundreds of thousands to tens of millions of users, and I have consistently focused on scalable, maintainable, and accessible user experiences.
I bring strong full-stack collaboration skills, working closely with backend systems and APIs, including REST and GraphQL integrations. 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. In leadership roles, I have guided cross-functional teams and supported strategic technology decisions.
Overall, I am a senior engineering professional who combines deep frontend expertise with product thinking, technical leadership, and a strong commitment to building reliable, user-centered digital experiences.
