I studied computer science at university and have 5 years post graduate experience developing iPhone/Android and PHP/Java web apps. I love developing software and enjoy the way working as a freelancer brings me into contact with clients from around the world. I have developed a number iOS and Android native applications from initial conception right through to submission to the App Store or Google Play. I have also debugged and fixed projects that have been started, but no completed, by other developers. I use git for revision control and generally check in code every day so clients can keep a close eye on the progress of their projects. I have good practical English and communicate with clients over email, IM and Skype as well as bug trackers like Github , Bitbucket I believe understanding the specification correctly and maintaining regular communication are two of the keys to effective software development. I can almost certainly satisfy your requirements 100% and recommend you check out my reviews for some independent assessment.
