Hello,
I can assign a senior developer with over 7 years of experience with JavaScript, HTML5, OpenGL. I am sure we can expand the library, add the shaders and do all the other changes you need while working with your lead developer.
I own a software development company and with our 11 years of experience we are one of the best resources that you can find. We are based in Romania, our English is excellent and we are available on chat all day.
We can start work asap. If you need any kind of references or samples, we will gladly provide.
Please let me know if you are interested and maybe we can schedule a time for a conference to discuss this in more detail?
Best regards,
Adrian,
Lead Soft.
