What's the difference?

I have been developing full stack Ruby-driven web applications since early 2008, shamelessly capitalizing on the work of some awesome people via Rails, EventMachine, RSpec, Heroku, github and numerous third party libraries. Thanks and Kudos to you all :D

I love developing high quality software that adds a little something to people's lives and looks great while doing so. Want to make one? Let me know, it would be pleasure helping you!
