Depending on the direction of the projects I offer myself as a mentor (need
co-mentor(s) since I will be off-line for some time during the summer).

I have worked with Erlang/OTP for almost 2 years now - the last year full
time on a project which creates a telephone exchange where we have dealt
with encoding and decoding of Q.SIG (PSS1) plus the Q.SIG protocol stack
itself as well as an interface to layer 2 with a C-port.

If those experiences can be used contact me.
