It would be awesome if your friend would come out to DevTricks and talk about their technology stack and maybe some of the technical hurdles they are facing.
Talking at DevTricks is an excellent way to find other developers. If they don't meet someone at DevTricks I am sure that people at DevTricks will spread the word.
Tonight would be perfect because we have open slots but I understand how short notice that is.
I am looking forward to hearing about the success of this Niagara-based software company.
