part of JBoss, and over time he have been involved in alot of projects
at JBoss, mainly focused on the tooling/developer aspects.

need tooling. It's given him a unique viewpoint of being an actual user
of the technology - feeling both the pains and joys of a user.

in directions of the tooling and as such is now trying to make Ceylon
