I contributed several pieces of code to erlexec without having any idea of just who he was, only later realizing it when I read the Michael Lewis piece on him.
He's a very friendly guy and was quite willing to work with me on the patches I contributed to erlexec.
Here is his Github account:
https://github.com/saleyn
You can find his posts on Erlang's mailing list once a while.
Two of his interesting project I am following:
https://github.com/saleyn/erlexec -- a utility to control OS process from Erlang.
https://github.com/saleyn/eixx/ -- Erlang to C++ interface.
