About Mark McSpadden
Mark McSpadden is a husband, father, and programmer that enjoys referring to himself in the third person. (Not really, he thinks it's kind of silly.) He has spent the last 9 years building things for the World Wide Web and remembers when people actually called it that. For the last 6 years, he has been using Ruby and Rails to solve problems and benefit humanity. (Really...humanity...man he sure does think highly of his work.)
He is currently employed at one of the largest players in the airline industry where he works at trying to improve both B2B and B2C communication and information flows while secretly trying to prove that rapid development (and Ruby) have a place in the "Enterprise" environment. He is also the recent winner of the O'Reilly/Fluidinfo Writable API Contest where Book Chirpa received first prize.
