I am the author. At the time of hiring I built few simple apps but my knowledge was really limited. Of course I didn't knew that :) This knowledge gaps had to be filled: - ActiveRecord is not replacement for SQL, it's just abstraction. Try writing complex query in rails, good luck. - You can't learn practices for maintaining code if your app is 200 LOC. - Reading someone else code is different than reading yours. You get real experience by building apps for clients.
