Front-end engineer building accessible, performant React and TypeScript applications.
What I'm looking for
I am a front-end engineer with 5+ years of experience building accessible, user-friendly applications using React, Next.js, TypeScript, and Redux. I lead UI efforts cross-functionally, own component libraries, and drive performance and accessibility improvements that measurably reduce errors and increase usability.
I have launched customer-facing products and tooling—including browser extensions, plugins, and SaaS platforms—while collaborating closely with leadership and CTOs to integrate APIs, optimize performance, and maintain robust test coverage with Jest and React Testing Library.
