Crysfel Villa

Crysfel Villa is a Software Engineer with more than 7 years of experience with JavaScript on a daily basis. He started his career as a Web Developer working with HTML and basic JavaScript in the late nineties, but then he started focusing on Server Side technologies, such as PHP and Java J2EE.

Before he started working with the Ext JS library he loved to work with MooTools, but in late 2007 he started learning about an awesome new library that was emerging as an Open Source project. At that time the version 2.0 of the Ext JS library was just coming out and Crysfel started using this new library for medium-large projects in the agency that he used to work with.

In early 2010 Crysfel started working as a freelancer, he began to train teams on Ext JS for private companies, writing a blog with tutorials, tips and tricks, developing custom components on Ext JS for his clients, and working on Open Source projects to share his knowledge with the world.
