Here is what we do: - iOS (Objective C + Swift 4) - macOS (Objective C + Swift 4) - Android (Java + Kotlin) - Xamarin / Visual Studio (C‬, MvvMCross) - Graphic Design, UX/UI, Illustrations - Testing / UI Testing Page 2 of 8 - Unity 3D + Augmented Reality - 3D models and animations Over 10 years of work as a company, I carefully selected team members who are ultimate professionals in their sphere and absolutely reliable. We are able to do full stack development from enterprise solutions to startup projects. We can deliver any complex solution using any external platforms and libs if client requires it. We are the killer team of gurus who work extremely fast and coordinated. Our secret is that we do more work in less hours, because we use our own agile process and our own payment system. Our agile process coordinates people very efficiently, so that nobody is waiting for anything and is not blocked by anyone. Our smart automatic payment system sends money to every member of the team every evening, so they are highly motivated. We use machine learning and artificial intelligence for those two systems. And they only get better over time. Our payment technology is not time-based, it is value-based system. More valuable tasks are paid higher, as a result our people start from hard tasks and this speeds up the project dramatically, by discovering hidden problems early in the process. Our rates are not low, but we save a lot of time due to highly efficient process. As a result our clients spend much less budget and deadlines are always respected. As a client you can expect twice less budget and project duration. Over the years we have successfully delivered over 220 private and B2B mobile projects on time and within the budget.
