Hello I Have been creating high quality and excellent mobile applications for 5 years. During the period, I acquired many experiences that I use various mobile development frameworks and I became an expert engineer with expertise of the mobile applications. -iPhone/iPod/iPad, Android, Web Service,Ajax,XML,JSON,RSS,SOAP,WSDL -Social Photo/Video/Music App(Video/Audio Streamming,Photo/Video Editing) -MySQL,SQLite,HTML5,PHP,JSP -Facebook,Twitter -Location Based App(Google Map Service,Foursquare) -CoreData,CoreGraphics,Animation -Flurry,Testflight, lira, Basecamp, Dropbox If you are expecting such words as "High Quality", "Clean Code", "In Time Delivery" I would be the right person. If you can stand with "Memory Leaks", "Often Crash", "Low Quality", "Postponing the delivery" then I'm not your choice. I always try my best to be in the same line with the high technologies. You will be reported with the intermediate deliveries and project status every day and you will be able to take control over the whole progress. I can provide you with free bug-fix support for 1 month after submission of the app to the App Store. And if my project is not satisfied for you, you will be guaranteed 100% money back soon. Best Regards.
