In 2012, I remotely participated in two client/desktop MMORPG projects:

• At the request of the client from USA, I explored the source code of the game Star Sonata 2 (server on RakNet and client on Irrlicht engine), profiling and debugging. Identify and fix all bottlenecks and bring the FPS (frame per second) up to where it should be.

• At the request of the client from Philippines, I explored the source code of the MMORPG GraveYard Ran Online Spirit Server (server and client on their engines) and made various changes to the source code of the game client, including fix sprite engine (RHW projection is replaced by pure sprites).
