I am the author of these projects:
- HyperFrameset - The way HTML Framesets were meant to work - like super-stylesheets with seamless frames, document transforms and configurable routing. And history.pushState.
- preAMP - Use the AMP-HTML engine without giving up on valid HTML.
I have also contributed to MathJax - beautiful math in all browsers - which is used by math.stackexchange.com.
