Hi,
I have been developing games, Augmented reality apps, Virtual reality apps since past two years! I use Unity 3D gams engine for development.
You should first checkout the reviews I have got from my previous clients :)
You can also see from reviews that I have a pretty good experience of VR. I have worked on VRChat SDK too, which is the next level of VR social networking!
I personally like VR so I keep trying different things for Android to play in Google cardboard.
For Augmented reality, I use Vuforia SDK. I have an experience in doing almost all features of Vuforia.
For backend services I prefer to use Playfab SDK. They are providing awesome backend, in game news, IAP, leaderboard/stats management, authentication, etc. and it's FREE.. Check that out once..
I am looking forward two work on this project and would like to hear more about this project from you.
Please take some time to have a brief discussion on this project with me.
Thank you :)
