I have been following Coval on their slack, Michael Sullivan and Shannon Code seem like guys who just want to build something and not build the next scam.
I'll take a peek. Thanks for the tip. Suggestions on good developers are always welcome. I also have some interest in Steem's core developer (he writes excellent code) and we've exchange comments already on Steemit.

and even today I still can't find the open source repo.
