How to find a valid Node.JS Developer

  • Post category:article / News

Are you looking for a Node.js Developer but are finding it difficult to recruit one? Have you relied on recruitment companies but have not had the expected results?

In this article we explain who this figure is and what he/she does and the advantages of turning to Ricercamy as a partner in the search and selection of profiles in the IT sector.

A Node.js developer is responsible for writing server-side web application logic in JavaScript and/or its variants, such as CoffeeScript, IcedCoffeeScript, etc.


A bit of history….


Node.js was originally created by Ryan Dahl in 2009, some thirteen years after the introduction of the first server-side JavaScript environment, Netscape’s Web LiveWire Pro. The initial version only supported Linux and Mac OS. Its development and maintenance was led by Dahl and later sponsored by Joyent.

In June 2011, Microsoft and Joyent implemented a native Windows version of Node.js. The first build of Node.js supporting Windows was released in July 2011.

In January 2012, Dahl stepped aside, promoting colleague and npm creator Isaac Schlueter to manage the project. In January 2014, Schlueter announced that Timothy J. Fontaine would lead the project.

In December 2014, Fedor Indutny started io.js, a fork of Node.js. Due to internal conflict over Joyent’s governance, io.js was created as an open governance alternative with a separate technical committee. Unlike Node.js the authors planned to keep io.js updated with the latest versions of Google’s V8 JavaScript engine.

In February 2015 the intention to form a neutral Node.js Foundation was announced. In June 2015, the Node.js and io.js communities voted to work together as part of the Node.js Foundation.

In September 2015 Node.js v0.12 and io.js v3.3 were merged into Node v4.0. This merger brought the functionality of V8 ES6 into Node.js and a long-term support release cycle. As of 2016, the io.js website advises developers to return to Node.js and that no further versions of io.js are planned due to the merger.

In 2019, the JS Foundation and the Node.js Foundation merged to form the OpenJS Foundation.



Is Node.js a language?


Node JS is not a programming language, but it allows developers to use JavaScript, which is a programming language that allows users to create web applications. The official name is actually Node; it was originally designed to be used as a web application, but the author realised that it could be used for more general purposes and renamed it Node.js

Node.js is a cross-platform, event-driven, open source runtime system for executing JavaScript code, built on Google Chrome’s V8 JavaScript engine. Many of its core modules are written in JavaScript, and developers can write new modules in JavaScript.

Originally, JavaScript was mainly used client-side. In this scenario JavaScript scripts, usually embedded within the HTML of a web page, are interpreted by an execution engine embedded directly within a browser. Node.js, on the other hand, allows JavaScript to also be used to write code to be executed server-side, for example to produce the content of dynamic web pages before the page is sent to the user’s browser. Node.js in this way allows the implementation of the so-called “JavaScript everywhere” paradigm, unifying the development of Web applications around a single programming language (JavaScript).

Node.js has an event-oriented architecture that makes asynchronous I/O possible. This design aims to optimise throughput and scalability in web applications with many input/output operations, and is also great for real-time system web applications (e.g. real-time communication programs or browser games).

Node.js is a distributed open source development project managed by the Node.js Foundation and facilitated through the Linux Foundation’s Collaborative Projects Program.

This tool is mainly used by programmers who use JavaScript to write server-side scripts. Node.js is an open source, cross-platform runtime environment for executing JavaScript code outside of a browser. Every Node.js user needs to know how to interpret existing API codes to adopt their use in their projects. In short, they need to handle interactions between multiple systems. Therefore, excellent skills in understanding and creating custom ReSTful APIs are essential in Node;




Is Node. js the best framework?


From a user survey report, 4 out of 5 back-end and full-stack developers rate Node. js as their top choice. It offers software engineers unique toolsets to develop different use cases without wasting time or burning extra money on web app development. The networking model on which Node.js is based is not that of concurrent processes, but event-driven I/O: this means that Node requests the operating system to receive notifications when certain events occur, and then remains in sleep until the notification itself: only then does it become active again to execute the instructions foreseen in the callback function, so called because it is to be executed once the notification is received that the result of the processing of the operating system is available. This networking model, also implemented in the Event machine library for Ruby and in the Twisted framework for Python, is considered more efficient in critical situations where there is a lot of network traffic[1


What specifically does the Node.js developer do?

The main technical skills are

very good knowledge of Node.js, implemented in Typescript –
good knowledge of REST, Redis
very good knowledge of APIs and micro-services architectures – good knowledge of REST, Redis – good knowledge of Docker, Kubernetes
– good knowledge of Google Cloud (preferred) or AWS
Preferred skills: – PHP – domain driven design – distributed databases
At least 5 years’ experience in the field, during which the above-mentioned technical knowledge was applied and several projects were managed simultaneously, is required.



Obviously important soft skills, such as good teamwork skills, ability to multitask and manage priorities, attention to detail and methodicalness, complete the profile. Analysis and problem solving skills, flexibility and adaptability to the working environment, good communication skills are essential.

In the IT sector there is strong competition on the market and speed in contacting them and a study of salaries are the bases for optimising a selection process.

Ricercamy, a revolutionary and dynamic head hunter, born in March 2012, has, since its inception, been committed to introducing innovative elements into the world of Search and Selection that would improve the redemption of Recruiting activities.

According to a study by Linkedin, 75% of talents are passive and already working, not proactively looking for new professional opportunities. Only 25% of them are more consistently interested in actively searching for new job offers. Therefore, investing the company’s budget in subscriptions and/or offers from job posting platforms cannot be the only effective solution.

It is necessary to adopt a methodology that allows us to reach the best candidates: headhunting calls!

This is how our specialised headhunters find qualified staff for our clients.

Our consultants’ anonymous calls are able to intercept any profile with different seniorities.

Through a very thorough and technical pre-screening by telephone, in addition to the personal data, all the specifics about the candidate’s experience are collected in order to assess its validity and thus allow the candidate to access the next step.

All of the above is carried out and shared in real time via a cloud file in which it is possible to work hand in hand with the client company’s human resources representative, who does not have to wait 2-3 weeks to receive the first shortlist of valid profiles, but just a few hours!

Transparency and immediate sharing is a distinctive trait of Ricercamy, which has specialised over the years in the search and selection of technical figures in the IT field, thanks to the development of specific skills and knowledge of the profiles sought and the reference market.

By searching for personnel on a daily basis, our headhunters have acquired know-how and specialisation in their sectors, which allows us to be leaders in this market crowded with recruiters.

On the strength of our tools, since its inception, Ricercamy has helped from the smallest IT Start-Ups, to the large IT Colossi in the selection of qualified personnel who are difficult to find and to place. Thanks to our SMART commercial offer, our clients ask us to carry out selections that they have always tended to do internally, but since we have certain costs and do not provide completion fees or exclusivity, they feel free to delegate to us the management of their vacancies, or those more difficult or repetitive activities, thus lightening their workload.

If you are also looking for these profiles, don’t wait!
