Hi,
I am a very experienced developer having good command on HTML5, Javascript, CSS3, Dojo, mobile application developement and Google App Engine. I can develop your mobile application using Dojo mobile toolkit and Google App Engine APIs.
Using Dojo I can create reusable and object oriented framework for your mobile application which is really very easy to maintain. Dojo mobile toolkit supports all the leading mobile platforms (Android, iOS, Windows phone, Blackberry etc.) and all the modern browsers. You don't have to worry about cross platform and cross browser issues. I can also write the website code such that it will work as native mobile application and also inside mobile web browsers, without any need to write mobile OS specific code for UI (Java for Anrdoid or Objective C for iOS for instance).
I have also good working experience on Google App Engine's JDO APIs (for persisting data) and Channel APIs (for notification, alerts etc.). I have implemented status monitoring applications for desktop browsers, mobile browsers and mobile using Dojo and Google App Engine APIs.
Please message me and I will send screen shots of my previous works. Thanks.
