What is a Ruby developer?

A Ruby developer is a back-end software developer who specializes in working with the Ruby programming language. They play a vital role in building the essential components of various applications, significantly impacting their functionality and performance. Their responsibilities include constructing databases and libraries, ensuring seamless functionality when users input data.

To create web applications, Ruby developers increasingly rely on the Ruby on Rails (RoR) framework, which has seen remarkable growth. Ruby on Rails utilizes the Ruby programming language and follows the Model View Controller (MVC) framework for server-side web application logic. RoR developers handle crucial tasks such as linking applications to online services and assisting front-end developers.

Ruby developers hold the key to shaping the core of any application, thereby enabling impressive user experiences. By adopting Ruby on Rails, they further empower themselves to excel in creating, maintaining, and enhancing web applications with ease. Their expertise and skillset contribute significantly to the success of diverse projects.

1. Tech recruitment platforms

Utilize tech recruitment platforms like Index.dev to find reliable and skilled Ruby developers. These platforms handle the entire hiring process, from sourcing to vetting, saving you time and effort.

2. Freelance sites 

For smaller projects or short-term needs, consider hiring freelance Ruby developers from platforms like Toptal, Fiverr, or Upwork. Keep in mind that while this option can be cost-effective, it may require more follow-ups and attention to ensure the right fit.

3. Job boards

How to assess Ruby developers

You can schedule an interview once you have thoroughly screened the resume and assessed a developer’s abilities and achievements. To effectively assess Ruby developers, follow these steps:

1. Review the resume

Start by carefully reviewing the candidate's resume to understand their level of skills, experience, and previous work. Look for relevant experience in Ruby development and projects similar to what you need.

2. Conduct theoretical knowledge assessment

During the interview, ask technical questions related to Ruby programming. Focus on core concepts, language features, and best practices. This will help you gauge the candidate's theoretical understanding of Ruby.

3. Assign a live coding test

Provide the candidate with a real-world coding assignment that aligns with the type of project they will be working on. Set clear expectations and a timeline for the deliverables. This practical assessment will give you insights into their coding skills and problem-solving abilities.

4. Ask general questions 

In addition to technical questions, ask general questions to understand the candidate's motivations, passion for Ruby, and compatibility with your team and company culture.

5. Check technology fit

Ensure the candidate has experience and familiarity with the specific Ruby technologies relevant to your project, whether it's Ruby on Rails or other frameworks like mruby.

6. Evaluate Test-Driven Development (TDD) knowledge

TDD is an essential practice in modern software development. Assess the candidate's understanding of TDD and their ability to write testable and maintainable code.

7. Review feedback and testimonials

Look for reviews and testimonials from the candidate's past clients or employers. Positive feedback can indicate their reliability and work ethic, while negative feedback may raise red flags.
