I'm a software developer (I code in Ruby), with an interest in systems thinking. Bitcoin mainly appeals to me for its practical benefits, but the hacker in my can't resist learning about the protocol and network.
I own my own software development company, PatchSpace Ltd, but its services are mainly me working freelance.
I did a presentation you might like: The BarCamper's Guide to Bitcoin
I gladly accept tips :-) payb.tc/ashmoran / coinhandle.com/ashmoran
