What We Do

NodeJS frontend, application & integration developers.

We build full-circle NodeJS servers & applications capable of speed and scale.




Node.js (or simply Node), is a runtime server environment that allows for the running of Javascript outside of an end-user's browser. In other words, it enables the use of Javascript within a server environment, rather than as a frontend language in the browser. Because Javascript is so powerful, Node.js unlocks unrivaled capability in the realms of custom server and application development. Node allows us to run Javascript outside of a client browser, making available the power of Javascript at the server or application layer. Javascript is well-known for its high level of flexibility and its ability to empower developers to create a wide range of applications. By leveraging Javascript at the server layer, huge possibilities become available for the development of data-heavy, extensive applications.

Node is able to run on a wide variety of operating systems, including Windows and Unix-based systems (such as Linux and macOS), which allows for ease of integration with existing infrastructure and the ability for web application teams to determine a best-fit solution.

Node.js itself is written in a combination of C++ and Javascript, combining some of the most powerful programming languages into a high-performance runtime.

Node is one of the most powerful runtime server environments, and as such can be used for the development of almost any type of server or application.

Node.js is used to power Javascript-based backend server environments. Javascript is traditionally a frontend programming language, but through Node.js it's possible to utilize the strengths of Javascript for the creation of powerful backend applications.

Advantages of Node.js

  1. Consolidate your tech stack

    Because Node is Javascript based, it's possible to achieve a greater level of consolidation and conformity within a technology stack when the frontend also uses Javascript. In other words, through utilizing of Node as a backend language, Javascript can become a dominant language in a tech stack, which offers unique benefits to applications where Javascript's strengths can be leveraged for the app's goals. For servers and applications that are data-heavy and often require asynchronous processing at a high level of performance, Javascript is often aptly suited. Node enables us to implement the capabilities of Javascript as a whole within the backend environment, allowing us to build a technology stack that makes sense for an application. Through consolidation of an application's tech stack in this way, implementation becomes smoother overall, development time is reduced, and maintenance becomes easier. With a backend and frontend both utilizing Javascript, functions can be standardized and reused between both the frontend and the backend. Overall, leveraging Javascript throughout an application's tech stack and development cycle has the capability to result in reduced development time and an enhanced level of reusability of functions and microservices for both the frontend and backend of an application.

  2. Good Level of Scalability

    At its core, Node.js was built to be scalable. 

  3. High level of Performance

  4. Asynchronous Execution

    Node has the ability to process multiple functions simultaneously, which is a big pro over legacy programming languages such as PHP. 

  5. Greater Level of Security

    Greater level of security compared to legacy backend apps built on technology such as PHP

  6. Speed

    Node.js is fast. With its ability to handle multiple concurrent requests, coupled with native support for asynchronous functions, Node is able to deliver speed that rivals competing environments. In addition to its caching abilities, this makes Node a very viable option for fast, high-performance and scalable web applications.

  7. Faster Development

    As Node offers the ability to implement a full-stack JS architecture, it lends to faster development from a greater level of code reusability. Most modern frontends today are built using Javascript in some form, and by utilizing JS on the backend it's easy to see how the development process can become more seamless between the frontend and backend team. Javascript as a programming language fosters rapid development and reusability, and these abilities are able to transfer to the backend architecture when Node is involved.


Node.js is positioned as a next-generation server environment, with its unique value proposition being its capability to run Javascript outside of a web browser. Compared to traditional alternatives, Node.js offers unparalleled power and flexibility in the development of custom servers and backend applications. Node introduces the ability to execute Javascript outside of a browser, enabling the use of JS for complex backend operations. The library offers a range of benefits compared to traditional server programming languages, not least the flexibility and data-centric nature that Javascript itself brings.

Existing web applications can be moved to Node.js through a process that we refer to as web application migration. This involves the redevelopment and reimplementation of an existing server or application as a Node-based alternative. Lots of legacy applications can be effectively redeveloped as Node apps, making it possible to take advantage of the gains Node brings in relation to data-heavy processing. Legacy backends such as those running on PHP, Laravel or Coldfusion are popular candidates for reimplementation as modern Node applications, and for good reason. We also see a lot of situations where an application was initially chosen due to high levels of accessibility, such as Wordpress, but over time it becomes clear that it’s no longer suited to the growing demands of modern applications.
