Hire deeply-vetted senior Ruby developers

Ruby is a high-level programming language used to design highly efficient and scalable software applications for multiple devices and platforms. As Ruby is one of the popular technologies among businesses, experts in the language are in high demand. However, it is not easy to hire senior Ruby developers who are the right fit for the team. This is the reason we have put up a comprehensive hiring guide to help you select the right Ruby developers by identifying the top qualities and skills.

A senior Ruby developer plays a crucial role in building complex web applications. Excellent knowledge of Ruby is essential because it directly influences their ability to build, enhance, or maintain advanced software systems efficiently. Senior developers need a detailed understanding of Ruby, its frameworks, testing tools, and debugging abilities to create efficient solutions.

They must also understand Ruby Gems and libraries which help in accelerating the development process. Due to these factors, you should hire senior Ruby developers with in-depth knowledge of the Ruby language.

The front-end layer of an application ensures the website or web application looks good to users. Hence, it is crucial to design your application in a way that is efficient and easy to use. With front-end development, keeping all UI/UX elements in mind is critical. However, it needs both experience and expertise. So, hire senior Ruby developers who have experience working with technologies like JavaScript, HTML, and CSS.

Basic familiarity with SQL is an absolute necessity when developing software. Although when it comes to Ruby, there might be no need to compose any SQL queries, as ActiveRecord does that work for the developer. But it is still necessary to understand the basics of SQL to read logs and comprehend what’s going on.

Besides, knowledge of databases like MySQL, Oracle, PostgreSQL, and MongoDB is crucial for effective data management in web applications. Therefore, try to hire senior Ruby developers who have an understanding of database technologies.

MVC is the design pattern of application architecture. The M or Model is used to handle data and logic, V or Views handles graphical interface, and C or Controller handles the user interface and application. The Ruby on Rails framework has an application directory with three well-defined subdirectories: models, views, and the controller. Hence, you should hire senior Ruby developers who are familiar with the MVC architecture.

Bugs are a regular occurrence in software development. Therefore, before any real-time release, it is crucial to do a quality check of the developed software. Even though companies typically have a separate testing team, you should hire senior Ruby developers who know the pattern of running the dummy commands and recognizing the loopholes at the initial stage. This can save a lot of time and effort for both the developer and the tester.

When you hire senior Ruby developers, ensure that they are familiar with code management tools like Git and also proficient in some of the functionalities, such as making a new branch, pulling and pushing code, etc. Version control tools allow developers to keep track of every change. If any mistakes are made, developers can compare the previous stable versions of the code and fix the error while minimizing disruption to other team members.

Object-oriented programming or OOP allows developers to create classes and its objects where objects are the real-world representation and classes define the object’s behavior. So, when you hire senior Ruby developers, make sure they are familiar with the basics like the difference between inheritance vs. composition, creating lambdas, and other OOP concepts.
