    Sencha Ext JS 5.1 / Sencha Touch Expert

    Thailand - Last active: 13 hours ago - Tests: 2 - Portfolio: 4

    The last 5 years of my career I have worked with products of Sencha (Sencha Cmd, Sencha Touch 2.3, Sencha Charts, Ext JS 3.4, Ext JS 4.2, Ext JS 5.x). I was fortunate to work with highly diversified range of tasks. The list includes: - upgrades of applications (Ext JS 3.4 -> Ext JS 4.x -> Ext JS 5.0), - mobile application development (Android, iOS, Sencha Touch), - using Sencha Charts, - integration of third-party libraries into Sencha products (OpenLayers, Highcharts, jQuery, Google Maps, Yandex Maps), - code testing in Selenium, Siesta, Sinon, YUI 2, - refactoring, - fully project reimplementation (rewrite a project from scratch, rewrite a project from JS to CoffeeScript), - consultations, - and much more. Javascript is one of the few languages that gives too much room for creativity, a space to express their thoughts. And unfortunately too easy to go far from the correct direction, from the decision to be easy to understand for other developers. That is why I firmly believe in the need to using hard coding standards and official recommendations. It's not important tha you are using for yours projects - PHP, RubyOnRails, C#, Ajax, XML, JSON, bla-bla... I just said you: Yes, I can do it! It's OK! I know well Git, worked with Subversion, used many task trackers: Jira, Redmine, YouTrack, and others, can't remember all.. Also my expirience included development of a mobile apps using Java for Android. If you need in one of the best, you're welcome!
