From Learn About the Ext JavaScript Library

Hi,

My Name is Jay and I'm the Owner of TDG-innovations, a web development and custom solutions company. I started out with EXTJS back when it was Yui-ext .32 in October 2006. I've used EXT to deploy at least two applications built solely in EXTJS and modifications to two websites. Please feel free to contact me via my website or the EXTJS Forums.
