Crysfel Villa

Crysfel Villa is a software engineer with more than 8 years of experience with JavaScript. He started his career as a web developer working with HTML and basic JavaScript in the late 1990s but then 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, version 2.0 of the Ext JS library had just been released, and Crysfel started using this new library for medium-to-large projects in the agency that he used to work for. In early 2010, he started working as a freelancer. He began training 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. More recently, Crysfel has been getting into new technologies such as Angular JS and React Native.
