Hello Shin! Thank you for being an excellent Evangelist! I know teachers like you are not easy to find. I appreciate your time, your patience, your ability to make Ruby on Rails interesting online 5-day codecamp. Have a nice day!

Mr. Shin covered everything on Ruby on Rails. I learned a lot from him. His code camp is very intensive and if you follow every lessons and do lab exercises, you will be in no time , become a professional developer.

I would highly recommend the Ruby on Rails bootcamp to anyone with some development experience. The material is relevant, up to date, and taught at a reasonable pace. There is opportunity for hands on experimentation, and the labs and walkthroughs make great notes on their own. After the bootcamp, I feel I have a great basis of knowledge in Rails. Thanks Sang!

The Ruby and Rails Codecamp was very informative. I learned many things application techniques that can be used at my current job. High quality code camp instruction, never a lull or dull moment during the code camp.

The 5-day Ruby on Rails Programming class led by Sang Shin has been great. I have been auditing the class all week thanks to Sang placing a notice on the SF Ruby meetup list and have learned a lot this week. I especially appreciate the 'create code, watch it fail, then flesh it out until it passes' mode of construction, the repetition of commands over the course of several days (after a while it starts to make sense), and the avoidance, for the most part, of using shortcuts so that we could see what' going on at a detailed level. There is a lot of material to pack into only five days, and I feel Sang did an excellent job of doing that while giving just enough time for students to do the exercises along the way. Thanks for this opportunity.
