I'm a JavaScript evangelist and a Software Engineer with more than 10 years of experience with JavaScript on a daily basis. I started my career as a Web Developer working with HTML and basic JavaScript in the late nineties, but then I started focusing on Server Side technologies, such as PHP and Java J2EE. Before I started working with the Ext JS library I loved to work with MooTools, but in late 2007 I 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 I started using this new library for medium-large projects in the agency that I used to work with. In early 2010 I started working as a freelancer, I 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 clients, and working on Open Source projects.I really love to share the things that I know, usually through my blog but I have also published a book about Ext JS and React Native :)If you want to find more information about my work, you can follow me on Twitter (@crysfel) or clone my Open Source projects from GitHub (crysfel).The following images show some of the work I've done, these are all personal projects that I did on my spare time.
Listed skills include Javascript, Jquery, Ext Js, Php, and 24 others.
