Hello, here is our portfolio http://meliorgames.com. 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 are outsource projects (business apps and games) that are closed for review due to signed NDA. We have rich experience in developing applications of different complexity for more than 5 years already and we are able and ready to create for you a quality bug-free similar to Presentation creator app. If you are interested, please contact us we will discuss the details. We will be waiting for your reply. Thanks. Best regards
