Hi,
I have been in app development in Sencha Touch v1 and v2 with Phonegap/Cueme wrapping for last 3 years. I have developed a number of iPad/Android tablet apps and iPhone/android phone apps in this time and have gained expertise in Sencha Touch, HTML5, CSS3 etc. Even, for meeting special requirements I had to develop custom components like flipper, vertical slider , tiles carousel etc and used those successfully in these apps. That is why I can confidently say that I can design and develop this required demo app for iOS/android etc devices . I completely assure to provide a high quality app which will run efficiently in all types of devices. Please let me know if you are interested in working with me. Also please let me know if you have any question.
Thanks,
Ayan Dasgupta.
