The Hadean Platform offers a HPC backend for running games & simulations, used in the defense industry and MMORPGs.
It enables a game to use multiple servers transparently, so that a player/client sees them as one large server, enabling tens of thousands of users visible at a single location.
As part of Hadean, I've worked on two different MMORPGs (Yuga Labs' Otherside & YOURE.UNIVERSE).
Apart from general gameplay development, a major task of mine was integrating the Hadean Platform into the game's multiplayer, to ensure servers could be clustered together. This most recently culminated in a successful test with thousands of players (see below).
I've also worked on improvements to internal processes, tools, and the HPC backend itself.
