Ruby Developers Hiring Guide

One of the most loved tools for web development

Ruby is a general-purpose, dynamic, interpreted language for object-oriented programming. It was created by Yukihiro “Matz” Matsumoto by blending parts of different programming languages, mainly Perl, Smalltalk, Eiffel, Ada, and Lisp.

Ruby is an intuitive, easy to follow, and flexible tool for developers all across the world. It’s about as simple as Python but with the additional benefit of being extremely customizable. Ruby’s syntax is so human-like, that even a person who doesn’t know about programming languages can to some extent understand code written in Ruby.

Ruby is perhaps more well-known for Ruby on Rails, an open-source framework for web development used to build apps like GitHub, Zendesk, Shopify, Airbnb, SoundCloud, and more. It’s a powerful and loved framework that sticks to its motto “a happy developer is a good developer ”.

It’s cost-effective, easy to use, safe, built on the notion of good practices, and has one of the most devoted communities in the business. Sure, Ruby on Rails might not be the most flexible framework, but it’s one of the quickest, as you can go from prototype to production in record time.

Even after all this time, few frameworks offer the same amount of “ready-to-go” tools like Ruby on Rails, making it one of the best options to build a web application. In fact, Rails is so widely used that companies looking for Ruby developers mostly do so because they need talent that can work with the framework.

How difficult is it to find good Ruby developers?

Not difficult at all. Ruby is a mature technology that has been on the market for over 20 years, and thanks to how influential Ruby on Rails is in the web development world, the job market for Ruby developers is filled with developers with all levels of expertise.

In fact, if there is a hurdle at all, it’s that many Ruby developers have been working in the business for a long time, so much so that many of them are better suited for positions such as project managers or senior developers. So it is slightly easier to find someone with experience than someone starting fresh. But just slightly.

How to choose a Ruby developer for your project? 

The main thing you have to clarify is why you want a Ruby developer. While Ruby has become synonymous with web development, let’s not forget that it’s an all-purpose programming language, and a fine one at that.

Usually, when people are looking for a developer for a specific language it’s because:

  • They’ll work on a product that was built using that language.
  • They are filling a position in a development team that is already developing a project with the language.
  • They are building a new project and are interested in using some of the tools available for that language.

Whatever the case, having experience in your field or with similar projects as the one your team is undertaking is an important asset. Of course, the candidates also need a solid understanding and plenty of experience with Ruby.

It’s important you think about the position they are filling. If they are going to be leading the team, or if they are coaching less experienced developers, look for senior developers and candidates with previous leadership experience.

One of the greatest aspects of working with Ruby is that it’s highly customizable: it really can be shaped by the developer as they see fit. Candidates who show creative and divergent thinking are specially fit for working with Ruby.


Maybe you want a developer to work with Ruby or Rails, or maybe you just want to use Ruby to power your project since you’ve heard how easy it is to use. Either way, there are plenty of developers out there from all walks of life who are part of the Ruby community waiting for an opportunity to help you move towards your vision.

What is the difference between nil and false in Ruby?

  • Nil isn’t a value, while false can be a value
  • Nil is always returned when there is no predicate, while in the case of a predicate, true or false is returned by a method.
  • Nil is not a boolean data type, false obviously is.
  • Nil is an object of nilclass, false is an object of falseclass

What is the use of load and require in Ruby?

In Ruby, load and require are used for loading the available code into the current code. Load is recommended in cases where loading the code is required every time someone hits the URL of an application. In the case of autoloading, it’s suggested to use 'require'.

What is Ruby on Rails?

It’s a framework for developing web applications. It’s by far Ruby’s most popular project and it was one of the first frameworks to popularize the MVC architectural pattern that’s become a standard in the industry. One of its biggest advantages is that Ruby on Rails comes with WEBrick providing a simple yet quite functional HTTP web server from the get-go.

What are the principles of Ruby on Rails?

Ruby on Rails has 2 core principles:

  • Don’t repeat yourself: For RoR developers every code snippet should have a single authoritative submission within a system. When developers follow this principle they end up with a cleaner code and fewer bugs overall.
  • Convention over configuration: This just means that the framework and libraries used are “opinionated”, i.e., the framework should reduce the number of decisions a developer has to make without losing flexibility.
