Team Lead at Hyves Games v1.0
Ah, the good old Flash days...
We built a Casual Multiplayer Game Engine, dubbed Loki, that ended up being the first Hyves games portal, hosting over a million multiplayer games per week. This was in 2009, when Hyves was still a big social network in the Netherlands and multiplayer casual gaming was a new thing.
We built seven realtime multiplayer casual games as proofs of concept for this Loki engine. Then we had exactly two months to take that system to production and it became the original Hyves Games platform. Fun times.
