Dan Atkins is a web developer with 16 years’ experience based in the Greater Leeds Area, blending front-end polish with back-end tooling and specification work. He contributes to high-profile web standards projects—WHATWG, W3C CSS drafts and Web IDL—and has helped modernize core specs like the DOM by converting them to Bikeshed. Comfortable across the stack, Dan writes tests and parser implementations (CSS Parser API, web-platform-tests) and improves developer tooling such as the Bikeshed preprocessor. His work shows a rare combination of meticulous editorial clarity and practical engineering, from styling and visual tooling to mutable parser internals and serialization. Colleagues rely on him for making standards readable, testable, and maintainable while keeping an eye on long-term interoperability.
