I'm Josh Adams, the CTO of a mildly successful software consultancy that does cool stuff (isotope11.com). I'm an expert rubyist and have built systems that handle a billion plus worth of transactions per year (I sadly do not get a cut). I've architected large projects for customers ranging from state agencies to federal agencies, and built tons of startups' apps.
Having said that, I'm new to Erlang and newer to elixir (though I have built an actor model based financial trading platform in ruby with celluloid). The premise of the series is that I will learn elixir as a professional developer that is very experienced, and you will come along for the ride.
I'd be remiss if I didn't mention that this entire format is inspired by Avdi Grimm's RubyTapas. If you like this, you're bound to love RubyTapas.
