United StatesWhat I'm looking for
I am a senior front-end engineer with 18+ years building accessible, responsive web applications focused on React and TypeScript. I prioritize WCAG conformance, component reuse, performance, and a clean developer experience to ship reliable products quickly.
I have led accessibility audits, authored Accessibility Conformance Reports, and built reusable component libraries and design-system-driven UIs that reduced defects and sped releases. I collaborate closely with design, product, and QA, and I have experience integrating APIs, prototype AI/automation tools, and supporting cloud/CI workflows.
