Hello, my name is Rogerio.
I took a look at your project, and it seems to me that you are building something here.
I am a Full Stack Web Developer and I do not have a vast or rich as you said, experience in 3D Applications, I have already messed with BabylonJS and actually I just started to read the book of one of their founders, who actually was responsible for the engine you are using now.
So, maybe I am not the right fit for the job, and not exactly what you are looking for but I could not help myself and bid.
I would like to invite you to a chat, for an interesting discussion, even if you are not inclined in hiring me, this is one kind of a project, and I just cannot miss it.
Best Regards
Rogerio Dalot
