There may be a good chance you may already know me.
If you don't, here I am. A veteran in the SFDC community and ex-engineer at Salesforce.com. Having spoken at a lot of meet-ups and conferences does make me an evangelist of salesforce.com.
An evangelist of anything I believe by birth and having coded 100+ prototypes, gives me enough credibility to at least train people on this kickass platform.
