an expert in opengl is needed

We have 15+ years of experience in game development. We started game developing using native 3d platform such as opengl, directx. So we are very familiar with opengl, and we can even write complex GLSL. I'm sure your proposal will be finished perfectly. We expect your reply. Best regards.
