Job in progress

Development of Russian Word Game

/ $4,444.44 (fixed-price)

Sergey is part of a small team who created our app "Game of Words". He has mostly been responsible for server side tasks, but also a few tasks for the iOS version of our app. The end result was beyond expectations, so I can highly recommend Sergey and his team to anybody who wants to make games. We are already making plans to work with Sergey again.

Mobile Game Developer

/ $2,167.00 (fixed-price)

I like to give honest reviews, and must say Vitaliy is overall the best contractor I've worked with. He has both been the main programmer and manager of the rest of his small team in Factorial Complexity. He was responsible for the full development of our app "Game of Words" both for iOS and Android. The end result turned out to be above expectations.The project took a little longer than expected, so I only gave 4 stars for "set reasonable deadlines". However, I would give 6 stars for everything else if it were possible. Even though Vitaliy completely underestimated the scope of the project, he still stuck to the agreement and over-delivered the end result, even though this meant working for free in the end. So in other words, a very honest and talented guy who delivers high quality projects and provides excellent communication. We already have plans for further collaboration.
