What to look for in a Ruby on Rails developer

Firstly it is important to know that Ruby and Ruby on Rails are not one and the same. A Ruby on Rails developer will require knowledge of Ruby, but this is not always the case the other way around.

Ruby is a general-purpose programming language and Ruby on Rails is the most widely used framework within the Ruby language. Ruby on Rails is used to code web applications and the back-end of mobile apps and is often used in business applications.

The most important thing to look for in a Ruby on Rails developer first and foremost is knowledge of the language and the framework. It is also important for your candidate to be up to date, a candidate should be familiar with the latest versions of Ruby and Rails. Another important trait is showing skill with coding.  A unique trait of the Ruby on Rails framework is that it enforces test and code quality, meaning that only high-quality code gets through.

Finally, your Ruby on Rails candidate should have at least one year of real commercial experience using the framework, as there can be a big difference between personal projects and commercial projects, and candidates who have contributed to Ruby on Rails open source projects are particularly valuable.
