This looks like a great presentation to me. My only feedback is that you should try to pitch it in a way that minimizes the tools aspect of it. For devopsdays this year we are really looking for talks about more than just tooling.
Anyway, I suggest tweak your description a little bit and submit it to the conference. Also try to make it obvious that you're a developer - there's a general feeling that devopsdays is too ops-heavy, so we are really trying to reach out to developers too. That's a big reason I first thought of contacting you. :)
