What I'm looking for

I’m open to remote roles and value work where I can build scalable component architecture and accessible interfaces, while applying front-end or back-end solutions as the problem requires.

At 3M, I co-built and maintained a shared React component library adopted as the UI standard across five teams, with accessible components, design tokens, and Storybook. I owned its semantic-versioned releases.

I was the team's accessibility implementer across the Product Catalog, storefront, and design system, working with ARIA, keyboard and focus management, semantic HTML, and screen-reader correctness. I also helped bring a slipping Product Catalog project to its 90% release-gate test coverage.

I built Sportico, a live field-booking platform for football fields in Costa Rica, using Next.js, TypeScript, Node.js, and PostgreSQL. Its Lighthouse scores are 100 for Performance, 96 for Accessibility, and 100 for Best Practices and SEO; I’m now offering it to clients.
