My passion is build amazing Ext JS projects, what I'm doing the last six years of my life. I provide clean, standardized code that is easy to maintain, update, expand and reuse. If you are looking for somebody who responsible, to hire once and never worrying again about quality and terms - it's me. Check my feedback history to be sure these are not empty words, or check "Top 11 World's Best
Ext JS Freelancers" by Upwork version - I am the first almost each week.

Worked with all versions from Ext JS 3.4 to Ext JS 6.2, included Sencha Touch, Sencha Charts, deep knowledge of Sencha Cmd.

My experience with Ext JS about 7700 hours.

I was fortunate to work with highly diversified range of tasks:

• migrations and upgrades of applications (Ext JS 3.4 - Ext JS 4.x - Ext JS 5.x MVC - ExtJS 6 MVVM),
• mobile application development (Android, iOS, Sencha Touch),
• using Sencha Charts,
• integration of third-party libraries into Sencha products (like OpenLayers, Highcharts, jQuery, Google Maps, Yandex Maps, Telerik),
• code testing in Selenium, Siesta, Sinon, YUI 2, Sencha Tests (soon)
• refactoring,
• fully project reimplementation (rewrite a project from scratch, rewrite a project from JS to CoffeeScript, from MVC to MVVM, from Ext JS 3.4 to Ext JS MVC),
• consultations about architecture, developers, solutions,
• and much more. .

Great and deep Git abilities, SVN experience.

Do not hesitate to ask details.
