Het Bijstere spoor
My name is Evert Pot, and you're looking at the 6th reincarnation of my web presence.
I'm a programmer, mainly working with PHP and JavaScript.
I'm involved with the PHP Framework Interop Group, I'm the lead developer for SabreDAV, and I'm one of fruux' co-founders and CTO. In the past I played a similar role at filemobile.
I'm available for consulting as well. If you're into that sort of thing, you could take a gander at my resume.
I'm a console junkie, I love good software architecture and I still remember my ICQ number.
