I know Unity3D inside out, including C# Scripting, Physics, Mecanim, AI, Custom Editor - pretty much every part of it.
I ported games to iOS, Android, Web and Desktop platform with all native features including GameCenter Leaderboard, Achievement, and IAP.
I integrated Admob, Chartboost, AdColony, Unity Ads, AdSense and IAP into games for max profitability.
I used Photon Unity Networking to create MOBA game with real-time multiplayer system that supports 3v3 Realtime Battle and Quest System.

I worked for the biggest internet company in China but it isnt that easy to find a professional programmer like him and has great communication skill as well. I highly recommend you to work with him!
Tung Yee Tang's skills with Unity 3D allowed me to develop my prototype much faster than I would have on my own. It was a pleasure working with him.
