I used to be a university professor before switching to professional software development. Probably this is why I still love helping people. I can help you with everything related to Ruby and Rails. If you have the performance or scaling problem, I'm definitely the guy to ask. Over the last 10 years I became an expert on optimizing Rails applications, and, as the result, wrote the Ruby Performance Optimization book (http://ruby-performance-book.com).
