I need a ruby on rails developer to help me out with a project. The work is straightforward, aside from the initial setup, and I will walk you through the setup steps. The work needs to be done in test-driven iterative style, the datastore is mongodb, and the repo lives in github. You should be familiar with rspec, git, ActiveRecord, erb, and general software development practices.

In your response, please answer the following :

1. What’s 14+6/5?
2. What is your os? What text editor do you use?
3. In ruby, what does #call method do?
4. How do you run a raw sql query with active record?
5. What is a typical location of the bundle?

Thanks, I look forward to reading your submissions!
