Google Firebase - Mobile OTP needs to setup on iOS Unity3d

Hi, Nice to meet you! I'm a Unity3D professional. I have also skills such as C++/C# programming, Game server programming, DirectX and Game AI programming. etc. I had been experienced Car racing game, online horse-racing and truck simulation projects and so on. I'd researched about AI of high level Game agent/bot by using FSM(Finite State Machine) and fuzzy logic, and implemented it. And I have also manipulated many physics problems at the car/truck racing game by using PhysX SDK .etc. In specific, I'd participated the development of rigs of rods v0.36.3, the excellent vehicle simulator in 2008. Also I have fundamental knowledge and potential ability to solve any technical problem of another programming. For Unity I've been developing with it since 2011, when its version is 3.3. So I have confidence and a lot of experience in my work on Unity3d. I think and sure my ability will be matching your needs perfectly. I promise faithful and hard work and expect long term assignment in the future. Thank you for your attention.
