Top expert inJavaScript Ecosystem Development
Nicholas Zakas is a freelance software engineer with 15 years of experience specializing in web technologies—JavaScript, CSS, HTML—and deep expertise in accessibility, performance, internationalization, and scalable, maintainable architectures. Creator of ESLint and a prolific open-source contributor, he has shaped core tooling for JavaScript and TypeScript (including parser work in Acorn and typescript-eslint) and improved security practices through rule development in eslint-plugin-security. Based in Boston, he combines hands-on engineering with coaching and technical leadership to guide teams toward robust code quality and developer experience. Less obvious: his contributions span both low-level parser correctness and high-level UX of tooling, reflecting a rare blend of language-spec fidelity and practical developer ergonomics.
