How can you hire a MERN Stack Developer?

There are three approaches to hiring a MERN stack developer. These ways are as follows:

A. Freelancers


This method is the most affordable out of the three options. However, you might not be able to get the same MERN Stack developer later in case some bug or issue arises. Thus, contacting the same person to work on your project will be difficult. Moreover, your data security is at risk too.

B. In-house Developers

These developers are your employees only and can dedicate their entire time to your project. Moreover, if any issue arises in the future, you will always have a MERN stack developer at your disposal. Furthermore, data protection is not an issue in this case.

However, suppose you hire permanent employees for one project only. In that case, it might become expensive as you must pay them monthly salaries even if the work is finished.

C. Outsourcing

Outsourcing is the third method of obtaining a MERN stack developer for your project. In this approach, you go outside your company to another organization to complete your tasks.

This option demands less time and money. Thus, several companies like to opt for Outsourcing. Therefore, if you have a short-term project and want to get trained developers immediately, you can go for outsourcing developers. 

We will take you through the steps of hiring a MERN stack developer via Outsourcing.

Step 1: Send in Your Project Requirements

When you opt for Outsourcing, you will need to send your project requirements to the organizations whose developers you want to work with. Doing so will help them discover the resources necessary to fulfill your project requirements.

This way, you can evaluate and select the ones that perfectly fit the bill with the help of the interview round. Here you can test their knowledge of the said technology.

Step 4: Finalize a Payment Model

Once you select all the developers with whom you want to work, you will then be required to determine which payment model suits you and your business needs. Generally, companies have full-time, part-time and hourly models.

Step 5: Onboarding

The last step involves onboarding your chosen developers or a development team by giving them the required resources, equipment, and infrastructure.

Since you know how to get a MERN stack developer for your projects, are you excited to start?

Out of the three ways of acquiring a MERN stack developer, Outsourcing is the easiest as it is affordable compared to in-house development.

Moreover, you will also need to train your developers in the second approach.
