Amazon AWS S3 IOS upload issue (First attempt fails, second succeeds)

Hi there, I'm a mobile applications development team manager and a developer myself too, and I'm very interested in your job post involving these skills. We have recently worked in iOS/Android/Windows Phone apps development and we have also User Interface design and Graphics design skills too. Our team also has so much experiences in Web/server development. We have consistently delivered projects on time and under budget, which has earned us many positive ratings, as you'll see in our work history, a number of our projects are in our freelancer.com portfolio. Some of our works are very similar to your requirement. We are available to chat via freelancer.com chat tool and your suggested chat tool, and would be happy to set up a convenient time to discuss the application you're moving and some ideas about the safest way to get it into the cloud. Thanks, Quy.
