How to find a React JS developer

When you’ve defined the level of front-end programmer you require, it’s time to determine the collaboration model that suits your needs. There are several options available.

The most known one is to find in-house React.js developers, which is ideal if you want direct and timely communication with the hired professionals. This solution is beneficial if you already have a development team and need additional developers full-time to strengthen it.

Advantages of this approach:

  • You have complete control over your team and the entire development process.
  • A full-time developer can resolve possible issues faster since your communication is direct and immediate.
  • An internal employee can better understand the company’s values and workflow.

Disadvantages of in-house recruitment process:

  • You may not find suitable candidates in your location.
  • You will handle all activities related to recruiting, interviewing, hiring, onboarding, and maintaining professionals.
  • You will have to pay more taxes for each new full-time employee.

If you find that a full-time employee is not the right fit for you, consider other options to augment your team with remote staff.


Hiring freelancers may be a suitable option for you to complete small projects or tasks.

One of the most common ways to find freelance React.js developers is through job posting sites. These platforms offer a direct line to your target audience, regardless of the type of developer you’re looking for. Many of these sites boast large numbers of applicants, making it easier to find a suitable developer quickly. This hiring strategy can save you time on screening and recruitment processes.

Online communities such as Stack Overflow, Dice or GitHub Jobs can be valuable resources for more niche jobs. Upwork is a popular freelance platform with a large pool of developers. Toptal, Indeed, and Fiverr are prominent players in the freelance market too.

Popular social networks, like LinkedIn, Twitter, or Facebook, can also be used to hire React.js developers. With some research and outreach, you can expand your network and connect with potential candidates.


Outsourcing can be ideal if your project requires diverse specialists, including a team of React.js software developers. In this case, you will communicate with a project manager who will take full responsibility for all project-related activities, update you on current issues and provide reports on the work done. The outsourcing company will handle all aspects of hiring competent specialists, determining their compensation, and managing taxation.

By outsourcing, you can access a broader range of expertise and resources, ultimately leading to a more successful project. To find a development company for outsourcing, search online, ask for recommendations, or check review platforms such as Clutch. These platforms provide valuable insights into the experience of other companies that have worked with the outsourcing company, allowing you to make an informed decision.


In hiring a remote React developer to work with your internal team, an alternative collaboration model to outsourcing is called outstaffing. This option is suitable when you want to handle the project management internally but need a software development provider to hire and maintain the team members. Using the services of an outstaffing agency, you get instant access to a vast pool of diverse specialists in front-end and back-end development. For example, if you need to beef up your React development team with a good server tech-savvy, look at the benefits of hiring a Java programmer.

Outstaffing allows you to quickly add highly skilled team members without the hassle of recruiting, and interviewing to check for expertise. Additionally, you can utilize the programmer’s services for the exact duration of the project and easily replace them with a more suitable candidate, if necessary, without the complications of salary, taxes, and layoffs. However, there may be significant differences in time zones and cultural norms, so choosing outstaffers from offshore locations close to your own, such as Ukraine, is recommended.
