    “I have been very happy with the work and professionalism that Rostyslav has displayed. He has displayed a firm grasp of the somewhat obscure domain (360° tours) in a short amount of time and has built the app beyond what I could have hoped in a short amount of time. If I need future iOS work done I will absolutely be using Rostyslav again. This app is open source (and I'm sure Rostyslav can point you to it to display an example of his work, I'm unclear on whether I'm allowed to link to work)”

Our refreshed team started mainly with Symbian expertise, but we supported also Win32, Windows Mobile. We grew later with Blackberry, Blackberry 10, Android and iOS and of course professional testing of solutions. In those perfect times we covered almost all operation systems.. Great times. Nowadays we keep experience and move forward with support mobile and server solutions. Our success formula is very simple: polite customers + professionalism in development + careful testing.
