In 2020, Forbes listed Node.js among the most effective backend web development technologies. Two years later, the platform is still at the hearing—with more than 6.3M websites using Node.js, it becomes the most widely utilized web development tool in the US. Global enterprises like eBay and PayPal that hire Node.js programmers have already considerably reduced the response time of their applications. Among the other value they gain are quicker product delivery, easier solution scalability, and faster pivoting.

The technology solves a lot of business challenges—so more and more vendors go nearshore and offshore to find skilled specialists. But what makes a seasoned Node.js developer? And how to choose a reliable vendor that will ensure the highest service quality from Product Discovery to the final release? Keep reading to discover these and other insights.

What are the essential features of qualified Node.js developers?

The number of Node.js programmers is growing as more businesses want to utilize the technology’s benefits. As a result, it might be challenging to pick the right experts for your project. Here are the criteria that will help you find and hire Node.js developers who apply the best coding practices and are able to develop robust web solutions of any type:

Hands-on tech skills

If you decided to hire Node.js developers, the first thing to pay attention to is their tech competency. Here’s a checklist of essential tools and expertise that seasoned Node.js programmers should possess:

  1. Node.js and Node.js API features (streams, events, http/net, buffers, memory profiling, and management);
  2. Multithreading (Cluster Mode, Worker Threads);
  3. Async programming (Event Loop) and runtime optimization (V8, libuv, ThreadPool);
  4. Databases, including:
    • Relational databases (MySQL, PostgreSQL);
    • NoSQL databases (MongoDB, Redis, DynamoDB);
    • ORMs (Type ORM, Sequelize, Mongoose);
  5. Web application frameworks: Nest.js, Next.js, Express;
  6. Frontend technologies, including JavaScript, HTML, and CSS frontend frameworks (React and Vue js and Angular);
  7. DevOps-related tools, namely Infrastructure as a Code software (Terraform, CloudFormation), and CI/CD pipeline tools (Jenkins, GitLab);
  8. Cloud platforms: AWS, Azure, Google Cloud Platform;
  9. Different types of tests, namely unit, integration, functional, and end-to-end (optionally).

Professional certifications

Do you want to partner with seasoned Node.js developers that will be able to implement complex applications with a diverse set of features? It would be a plus if you find engineers with professional accreditations—these prove that the expert possesses a broad range of skills around JavaScript as well as has the practical knowledge of the best practices. Among the popular accreditations useful for Node.js engineers are AWS Cloud, MongoDB and PostgreSQL certifications, as well as frontend-related certifications.

High qualification level

Another important aspect to consider when building your Node.js engineering team is the average seniority level of your tech experts. With experienced Node.js programmers by your side, you are more likely to come up with high-performance web applications without multiple redevelopments. To ensure effective and timely solution delivery, try to hire Node js developers of Middle and Senior levels with 5+ years of proven experience in the field.

For example, at N-iX, an average Senior specialist has over six years of experience, while Node.js developers of the Middle level—around five. The vendor’s Lead engineers have at least seven years of experience in building web applications in a Node.js environment.

Success story: Modernizing legacy solutions for a global stock image and media platform

The client is a global technology providing a platform for purchasing and selling high-quality assets and services for content-making, including images, video, music, and editing tools. Since the enterprise rapidly expanded its customer base with new users and corporate clients, they needed to perform an all-encompassing modernization of a large range of systems and apps.

N-iX has formed a strong team of Node.js developers to deal with the optimization of the client’s legacy application. However, during the thorough analysis of the existing tool, we concluded that the most effective solution would be to design and develop a new admin platform from scratch.
