Hello,
I have 8+ years experiences for developing unity3d games.
I have skills with c#, c, c++, javascript.
In the term of concept, I have skills with OOP, design pattern, multi-thread, mutex, socket network programing, linked list, coroutine.
I have experiences with model, mesh, material, animation, particle effect, collection, rigidybody and shader.
I have no experiences with photon server, but I can provide a MMORPG battle game using backend based on node.js and socket.io.
If you are not care what backend is used, I will complete your webgl game by using node backend.
Best Regards
