Hello, here is our portfolio http://meliorgames.com. Feel free to ask promo code or download lite versions of any our games on the AppStore and soon on the Android market too. Our company is providing highly professional business app and game development services for iOS/Android. In our portfolio there are only our own games presented where everything (graphics/programming) is our own idea and implementation, however the major part of our work is outsourced projects (business apps and other games) that are closed for review due to signed NDA, though we can provide you with the common idea of technologies used. We have rich experience in developing applications of different complexity including the educational apps and we can make for you an educational app for Android. We will be glad to learn the details of your project and possibly cooperate. The bid is a place-holder so far as we need to learn the details for bidding accurately. If you are interested in cooperation, please contact us. We will be waiting for your reply. Thanks. Best regards
