Benefits Of Using Ruby On Rails For Your Project

hire ruby on rails developers benefits

 

Before we dive into hiring Ruby on Rails developers, let’s talk about the technology itself. Why are we considering Ruby on Rails development? What are the business benefits of choosing this technology for your next project?

 

Faster Development

The Ruby programming language is on average faster than its competition, such as PHP and Python. Rails is Ruby’s framework that accelerates development by reducing the amount of code writing. As a result, you save money and deliver a high performance app in a shorter time.

 

Scalability

Scalability is something that every business requires, regardless of the industry, current size, and target audience. Even if you are small right now, you might expand quickly very soon, and you need to have the resources to react. Without the ability to scale up or shrink down, your app will fail to adequately respond to sudden traffic peaks, increasing the number of requests and the seasonal ups and downs in the user load. Ruby on Rails is a scalable technology that enables an immediate and timely reaction to traffic spikes as per requirements.

 

Versatility

The Ruby on Rails framework has a huge community support network that regularly contributes to its development. RoR has a large library filled with tools, functions, add-ons that can enrich your application and make it more advanced and versatile. Known as Gems, they allow Ruby on Rails developers to add functionalities and create high performance and feature-rich applications.

Security

Cybersecurity is one of the hottest topics in the software development world. Regardless of how well developed your app is, how attractive your product is to your users, how advanced the features are, if user data remains unprotected, you will eventually lose your audience. Data breaches often lead to significant reputational losses, as well as negative financial repercussions. Ruby on Rails provides a high level of security, even without extra coding. The framework allows for a secure development lifecycle with the use of default tools.

Skills of Ruby on Rails Developers

One cannot hire Ruby on Rails developers without learning what they do. So what does a Ruby on Rails developer do, and which skills are vital for RoR programming?

Technical Skills

What are the essential technical skills for Ruby on Rails developers?

01

Ruby on Rails

Hire Ruby developers who are well-versed in RoR syntax such as loops, classes, modules, etc., as well as knowledgeable in object-oriented programming. An average Ruby on Rails web developer should also be aware of the Model view controller framework and know how to use it. Finally, RoR developers are required to be familiar with the Ruby on Rails stack and perform operations such as POST, GET, PUT, etc., as well as have a sufficient knowledge base about REST APIs.
02

Frontend

Even though Ruby is a backend language, knowing how frontend works and functions is a great skill for an RoR developer. Obviously, a Ruby on Rails engineer does not require extensive knowledge of JavaScript and CSS, but having enough skills to understand frontend developers and efficiently collaborate with them is a huge plus.
03

Databases

Before you hire Ruby on Rails developers, make sure they can comprehend databases well enough to read and operate logs. Basic knowledge about SQL, PostgreSQL, and MySQL is one of the necessary skills required for a Ruby on Rails developer.

Soft Skills

Soft skills are also vital for smooth collaboration with your team and they play a major role in the software development process.

01

Communication

Ruby on Rails development requires a decent amount of teamwork and collaboration, which amplifies the importance of communication skills. Hire RoR developers who have good interpersonal skills and can adapt to the company's communication channels.
02

Analytical and logical reasoning

It takes longer to understand, conceptualize, and design a feature than to create code to execute it. Having advanced analytical and logical skills allows coders to create plausible concepts and quickly materialize them, without frequently starting from scratch.
03

Self education

The world of technology changes more rapidly and frequently than in any other industry. The ability to stay up-to-date with the latest trends and developments makes the distinction between a good engineer and a brilliant one. Hire Ruby on Rails developers who are willing to learn and self educate.

Cost of hiring Ruby on Rails developers

How much does it cost to hire Ruby on Rails developers? Hourly rates differ from location to location, and hiring a coder from Eastern Europe or Asia is usually cheaper than from the US or Western Europe. Salaries also depend on the Ruby on Rails developer skills and seniority levels, as well as the project complexity.hire ruby on rails developers rates

USA Western Europe Eastern Europe Asia
$75 - $200 $60 - $100 $40 - $70 $30 - $50

If you decide to employ a Ruby on Rails outsourcing company, our small salary overview will give you direction. In case your budget allows, you could hire an American or Western European RoR development company, if not, Ukrainian Ruby on Rails development teams are a great middle-ground between expertise and cost-effectiveness.

Hire Ruby on Rails Developers using the Right Model

In this section, we will take a closer look at three main strategies that can be used to hire Ruby on Rails developers. Your choice could vary depending on your business goals, budget constraints, and staffing, as well as your personal preferences. Let’s try to define different hiring options and pinpoint their advantages and disadvantages.

 

Hire Ruby on Rails Developers In-House

Hiring in-house workers is a traditional type of employment that is still relevant and has a number of benefits.

Advantages of In-house Ruby Developers
01

Dedication

In-house hiring implies that an employee will work exclusively for your company. He or she will devote all their time and energy to your project, without any distractions. Unlike workers who jump between two and more projects, an in-house staff is fully focused on your goals and spends their time on attaining them.
02

Simple communication

When you hire in-house Ruby developers, you get access to simple and straightforward communication channels. You and your employees share the same office space, follow the same time schedule, and perform in the same time zone. All of the above noticeably simplifies and streamlines communication flow, and enables simpler collaboration.
03

Corporate culture

In-house Ruby on Rails engineers become an integral part of the company, brand, and team. They can take part in internal projects, organize events, and represent the brand name and message. Employees can establish a real connection to the company and its products, inherit its values and vision. This connection creates truly loyal workers who will stick around and support your company even during a slowdown.
Disadvantages of In-house Rails Developers
01

Limited talent pool

Especially if you reside in a small town, you might face difficulties trying to find Ruby on Rails developers with sufficient experience. Some areas are not attractive for software engineers as there aren’t many software development companies, and RoR developers for hire do not have many options to choose from.
02

Elevated costs

In-house hiring is an official process that requires adherence to a bunch of legal HR measures. Your company is required to cover employee insurance, taxes, pay for office equipment and vacations, etc. All the costs that go into onboarding one person for Ruby on Rails development might be counterproductive for a short-term project.

Where to hire Ruby on Rails developers in-house?

Check out websites like LinkedIn, Indeed, CareerBuilder, etc. to find experienced Rails programmers. Your HR department will have to go through a large number of candidates to find a hidden gem and hire RoR app developers.

 

 

Hire Freelance Ruby on Rails Programmers

In this case, freelancers are remote developers who usually work per project. There are also benefits and drawbacks of hiring freelancers that we are going to discuss further in the text.

Advantages of Freelancing Ruby on Rails Programmers
01

Cost-effectiveness

As much as in-house hiring is expensive, freelancing is cost-effective. You do not need to cover office equipment costs, pension, taxes, etc. Freelancers receive an hourly rate multiplied by the number of hours they have dedicated to the project. Alternatively, you can agree upon a fixed price that a freelancer will receive after the project is finished and approved.
02

Large candidate pool

Freelancers mostly work online, which makes their location irrelevant for the collaboration. This aspect significantly broadens the search, as you can hire Ruby on Rails developers from all over the world. Having access to a large pool of candidates accelerates the hiring process and allows you to find someone who fits your budget.
03

Ideal for short-term projects

Hire a Ruby on Rails developer who works as a freelancer for a particular task or short-term project. This type of collaboration is perfect for freelancers as you can work out the compensation details and simply hire a developer for a small task that your team cannot do. Or perhaps your team is occupied with other tasks and does not have time to invest in another project. This type of project can be easily delegated to a freelancer.
Disadvantages of Freelancing Ruby on Rails Experts
01

Less control

This point is twofold: you have less control over the task or project that the freelancer is responsible for, and you cannot manage the freelancer’s work as much as you usually do. There is a level of trust that you have to establish when collaborating with a freelancer, and if it’s missing, your project might suffer the consequences.
02

Unknown level of expertise

Most freelancer platforms do not have any vetting processes whatsoever. As a result, freelancers can include any information they want, even false experience or education. You might hire a Ruby on Rails developer thinking that this person is a Ruby expert, when in reality they are a newbie. And even if the platform does force freelancers to pass some tests to be published on their website, you have no way of learning who actually passed the test, was it the person behind the account or someone else. Skill evaluation requires significant experience and knowledge, and we will elaborate on that later in the article when we explore the Ruby on Rails developer interview questions.

Where to Hire Ruby on Rails Developers Freelancers?

There are a plethora of platforms to hire RoR developers:

  • If you are willing to hire developers online, check out Freelancer and Upwork. These platforms conduct zero to little screening processes, including tests. Here you can find junior to middle specialists.
  • If you require a top Ruby expert, check out Toptal, a platform with a rigorous vetting process that consists of five steps. Only three percent of all applicants successfully pass the tests and make it into Toptal’s database. Learn more about Toptal and Upwork in our article devoted to studying these platforms and establishing their strengths and weaknesses.

 

Use the IT Staff Augmentation Model

hire ruby on rails developers it staff augmentation

IT staff augmentation refers to borrowing one or several specialists for the project duration. This type of hiring is also perfect for short-term projects, but as opposed to freelancing, the staff augmentation team becomes a part of your in-house team. They work for you and with you for the entire project duration.

Advantages of IT Staff Augmentation
01

Quality guarantee

Working with a staff augmentation agency adds an extra layer of security and reliability Your staff augmentation partner will guarantee the performance you agree upon and take care of all the paperwork and legal actions. You will receive the results you look for and you will be legally protected by contracts.
02

Rigorous vetting

IT staff augmentation agencies conduct a very thorough vetting process before they hire Ruby on Rails developers. If you decide to use their services, you will end up with top-notch professionals whose experience is proven. Unlike most freelancing platforms where you might encounter quite a lot of scammers, IT staff augmentation partners guarantee the creme de la creme.
03

Cost reduction

IT staff augmentation will also save you on expenses, especially in the long term. Your organization will reduce the cost of management overhead, as well as training costs. Your staff augmentation partner will take care of the training and onboarding, leaving you with no preparation tasks. Besides that, you can choose an agency that operates from Eastern Europe, such as Ukraine, and offers lower prices for the same job.
Disadvantages of IT Staff Augmentation
01

Remoteness

Compared to an in-house team, IT staff augmentation is still a remote option. Your communication processes and organization might suffer from having an entire team working remotely. However, this disadvantage is easily solvable with a good and professional IT staff augmentation partner that will ensure smooth and fruitful collaboration.

Where to Find IT Staff Augmentation Services?

Look for IT staff augmentation firms online and conduct a thorough vetting process. We recommend you to go through references and reviews, as well as a client list, to make sure the company knows what it’s doing and that they can be trusted. Visit the homepages of the best companies for Ruby on Rails development and check out their case studies. The key is to find a company that has sufficient experience with Ruby on Rails development services that fits your requirements and goals. If you are not sure, contact the agency and ask about their interview process and how exactly they evaluate their staff.

 

In-house developers vs freelancers vs IT staff augmentation: table of comparison.

In-house personnel Freelancers Staff augmentation
Cost effectiveness The most expensive model Cost-effective model Cost-effective model
Expertise Your HR and Team Lead will have to conduct several interviews to find the right candidate Depending on the platform, you might find someone who is not as experienced as he or she claims Top-notch vetting process guarantees seasoned experts with extensive experience
