Ruby on Rails developers are IT professionals who write, develop, test, and deploy new software and web applications in the Ruby on Rails environment. But what exactly does a RoR developer do, and how do you hire a RoR developer? Let’s look at what it takes to become a RoR specialist.

What’s Ruby on Rails?

It is a framework for web software development. It is implemented in Ruby, an internal programming language. Ruby was created in 1993 by Yukihiro Matsumoto and is a flexible and precise language. It makes it possible to organize the written code more efficiently. Ruby’s syntax is based on code blocks, so errors can be avoided when changing a string of commands.

However, the Ruby language did not become internationally known until 15 years later, in 2008, five years after it was merged with the framework Rails. Rails broaden the Ruby language in the same way as .NET, Spring, or Django extends C#, Java, or Python, respectively.

This combination led to the framework called Ruby on Rails (RoR). In recent years, ROR has grown in popularity among developers because of its simplicity and foundation of agile methodologies. Rails offers a complete set of features for developing and operating web applications, such as:

  • Connectivity to all relevant database systems
  • Controller implementation
  • Respond to requests from the WWW
  • Proprietary template functionality for data preparation
  • Proprietary routing mechanism to customize the behavior of requests and responses.

Ruby on Rails Developer Responsibilities

RoR developers often work for product companies or larger organizations in IT departments. More and more websites and applications are using Ruby on Rails, so the field of work for Ruby developers is expanding.

Ruby on Rails developers typically develop back-end components, linking applications to other web services, and assist front-end developers, integrating their work with the application:

  • Write, develop, test, and deploy new software and web applications in Ruby.
  • Develops back-end components and integrates them with interface components
  • Makes testing and enhancements to existing Ruby software
  • Creates software documentation
  • Offers specific Ruby tips and suggestions to clients
  • Creates, administers, and maintains APIs
  • Performs troubleshooting as appropriate.

Ruby on Rails Developer – Skills

In addition to solid Ruby on Rails and Javascript programming experience, a RoR expert should have several other skills. These include understanding web development, design patterns, and application security best practices. A RoR developer should also be able to analyze requirements and translate them into detailed specifications. Good math and problem-solving skills are also required. In addition, certain soft skills can make or break a good developer.

Developers often work with a team of people, so being an active and enthusiastic key player is ideal. They must also be able to adapt to the ever-changing IT landscape by staying on top of new launches and releases:

  • Good understanding of Ruby language syntax.
  • Knowledge of RoR and libraries (Resque or RSpec)
  • Knowledge of OOP
  • Interface technologies such as JavaScript, HTML5, and CSS3.
  • Familiarity with automated testing, continuous integration
  • Experience with APIs and their development
  • Knowledge of Mocking, MVC, RESTful
  • The capability to seamlessly combine various data sources and databases into a single unified system
  • Knowledge of basic application design principles.
  • Experienced with code version control tools such as Git, Mercurial, or SVN.
  • Enthusiasm for new technologies and methods
  • Pragmatism, reliability, and curiosity

Benefits of Ruby on Rails

Developing web projects using Ruby on Rails (RoR) is consistently faster than other programming languages. The development speed is known to increase by approximately 30 percent compared to other alternatives. This is possible thanks to a huge set of RoR tools, a large number of ready-made solutions, as well as simple work in the Ruby language. This language is distinguished by sociality. If a problem arises, then many specialists take part in solving it. When implementing their module, programmers necessarily share it with others in networks.

Ruby on Rails has a certain culture, although everyone can work in different directions using the framework’s standards. Thus, any project becomes readable for every specialist. This feature helps to get acquainted with the web project in the shortest possible time and continue working on it so that the development can be carried out by one team of programmers, and other specialists can make changes.

Development Tools

Automated testing of a web project will allow you to make a quality check before use. Other frameworks don’t have this feature, so they lose a lot. Caching is a very important stage in developing a large web project. There are many options in PHP, but no one can choose the best one. Ruby on Rails has the means to do this out of the box. Due to the presence of a large number of ready-made and standard solutions, this framework has everything you need for caching.

Localization makes it possible to translate a ready-made web project or at any stage of development into other languages. PHP developers cannot create an English version as it will be treated as a completely new project for them. RoR has configuration files with the necessary translations and other tools, without which the localization process is simply impossible.

Routing can be easily and quickly configured in Ruby on Rails, and you can also choose the type of address and section names. Changing the address in one place will automatically change the entire web project. Search engines will understand page addresses on ruby hosting because they are characterized by simplicity.

The incoming data validation is based on Ruby on Rails tools. With the help of standard tools, you can check the form that users fill out, such as the presence of a password or the correct spelling of e-mail. Working with databases is very simple and affordable because, thanks to the availability of regular tools and tools, all changes will be documented and securely stored in the repository.

Security is always high because when placing ruby, you can exclude SQL injections and XSS attacks. The developer cannot make mistakes since all parameters are escaped by default. Deploy is the process of placing an application on the Internet through Ruby on Rails hosting. With just one command, you can roll out a new version to the server.

Additional Ruby Development Principles

To create any web project, you should know version control systems. So, all programmers working with Ruby on Rails must own a distributed version control system called git. It is difficult for beginners to master this programming language. First, you need to have a good understanding of PHP.

Ruby on Rails allows for project management, and professionals should be fluent in Basecamp. The free Redmine management system will allow you to manage all web project development processes.

Some Myths

There is an opinion that it is impossible to find specialists who develop projects on Ruby on Rails. Of course, they are. It’s just that their group is insignificant because you should have a lot of experience in programming languages.

Many argue that RoR developers need to be paid a lot. It should be understood that true professionals in their field always have high fees. RoR employs only high-level specialists. There is a misconception that this framework does not scale. All projects that are built on Rails have never had scaling issues.

It is worth noting that the performance of Ruby can compete with PHP very well. But this does not play a special role because the main thing is page generation time. The main advantage of RoR  is the high project creation speed at an affordable support cost.
