San Francisco, California, United States
Summary
🤩
RockstarTantek Çelik is a seasoned web standards leader and founder with 17+ years driving HTML, microformats, and open web interoperability from San Francisco. As Mozilla’s Web Standards Lead and W3C/WHATWG representative, he blends policy influence with hands-on front-end work, notably adding microformat and h-card support to projects like Mozilla’s contributor directory and the Bikeshed spec preprocessor. He co-founded microformats.org, BarCamp, and the IndieWeb movement, and has a long history of shipping web platform features at companies from Apple to Technorati and Revision3. Tantek is pragmatic about semantic HTML and accessibility—replacing spans with <time> and integrating rel="me" are examples of his attention to structured data that quietly improve discoverability and identity portability. His career marries community-building and standards diplomacy with practical engineering, making him a rare bridge between browsers, spec bodies, and developer communities.
