Ruby on Rails Expert needed with heroku experience

Hi, its pretty simple for me but I have few questions to ask, knock me for further discussion, PLEASE DON'T AWARD PROJECT BEFORE DISCUSSION. Thank You!

Hi, thank you for your job posting. I read your job detail carefully and I think i'm a best contractor for you. Because I had developed many backend ios/android app before and mastered all branches of iOS development such as social integrate, XML/JSON paser RESTful/SOAP Api and so on. I'm also mastered Ruby on Rails. I'm a serious bidder. So don't worry about my skills and my ability. I will finish project as possible as you want. Best regard
