Alon was such a huge help, I cannot thank him enough.
At very short notice & with an average connection, he filtered through a HUGE rails/backbone/coffeescript app to help me solve my issue. I had contacted several mentors before him who were experienced enough, but not willing to filter through such a large app. He jumped straight in to help. He also made sure that I understood the solution, rather than just doing it himself.
I would highly recommend him, particularly for Rails, JS & Coffeescript problems.
