Also, to ensure that you’re dealing with the right developer, ask for past records or projects where they did for another client or company. Their past projects will help you understand the kind and level of Ruby on Rails developers they are.

Lastly, ensure that you hire from reputable platforms and sources. This is because unscrupulous platforms are most likely always going to harbor fraudulent developers who either have no idea of what they are doing, or are out to runaway with your money.
