Crysfel Villa

Software Developer

Crysfel Villa I'm a software developer with more than 6+ years of experience, when I'm not coding with JavaScript and Ext JS probably I'm writing a tutorial, playing my guitar or skating on ice.

Personal & Professional Profile

I always like to try new things, I like to know as much as I can so I’ve learned many languages over the years, I think knowing many languages and tools is good but I’m sure is better to be an expert on just one thing and that’s why I started mastering JavaScript a few years ago.

I also like to share my knowledge with everyone, I think the more you share the more you learn and that’s why I run a Blog about JavaScript and ExtJS. I also train people in Sencha Technologies and right now I’m writing a book about ExtJS.

Technical Skills

Before I started mastering JavaScript I was a Java JEE developer. I have worked with Spring, Struts, Hibernate and many more JEE tools and databases such as Oracle, SQL Server, MySQL, PosgreSQL.

Now I’m more interested on JavaScript, ExtJS, NodeJS, jQuery and many other JavaScript related tools.

Also I really like mobile development for iOS (iPhone/iPad) and Android, at the moment I develop applications with Titanium and Sencha Touch.
