RUBY ON RAILS GURU

I need an experienced ROR developer to create a server side reservation system and deploy it to heroku. The system will need to serve both web and mobile devices. The API and endpoints will be roughly mapped out right down to the data structures. The system will have to handle concurrency and Mutual Exclusion etc. Your code will be QA by an experienced ror developer after you complete about 20% of the project to make sure your standards are up to scratch. If you are interested and are very capable please get in touch.
