Peter-Paul Koch (whom everybody calls ppk) is a freelance web developer in Amsterdam, the Netherlands. He’s best known for quirksmode.org, a 100-page compendium of CSS and JavaScript browser incompatibilities. The site is used not only by web developers around the world, but also by browser vendors (such as Microsoft) who seek factual, hype-free reports on the capabilities and problems of their browsers. Based on his experience with working around JavaScript problems in all browsers he’s written ppk on JavaScript.

He has founded Fronteers, a professional organization for front-end developers that’s currently active in the Netherlands, but may eventually branch out to other countries.
