Be it a web or mobile app, a smart home system, or something completely different, chances are there will be a central brain that tells every part what to do. This is where we come in. We have experts for a myriad of technologies that are used on application back-ends.

Perhaps you already have someone that is comfortable writing back-end code, but your dream is just too big for a single person? Do not despair, we can handle that as well. Our developers are very team-oriented, quick to learn their way around a new environment and will be able to jump into your system and start swimming before you can spell C++.

Common Technologies

If you are just thinking about starting a project and are still browsing for the right fit, here are several options we would recommend you put some serious thought into, when choosing your back-end platform.


Node.js is an open-source, cross-platform JavaScript runtime environment for server-side execution of JavaScript code, which uses the Chrome V8 JavaScript engine.

Put simply, while, in the old days, JavaScript used to be limited to browsers, with Node.js, it can be used to write stand-alone programs that run on the servers as well and use the same JavaScript engine Google uses for Chrome, which supports many of the latest language developments.

Node.js has been around since 2009 and has since grown into a major player that supports Linux, OSX, and Windows environments, has its own package manager, and which has, through rapid growth, since reached major version 7 (current) or 6 (LTS).

It would be remiss to not mention the fact that Node.js is used by everyone, from the solo programmer, working on their pet project, to a megacorporation, which is building a system that will serve millions of users.

Node.js can thus be used in all kinds of projects. Be it a tiny microservice or a giant monolithic server, it can do it all.

There is no doubt that Node.js is an extremely versatile piece of technology. It has a huge following, a gigantic set of existing libraries, and it is very easy to setup and run in both a "traditional" server environment or with specialized containerized continuous integration systems.

But that is not all. One of its most important bonuses is that it is just "plain old JavaScript". This means that if you hire a dedicated node developer and then decide to have them learn front-end work as well, they will only have to learn the front-end library/framework stack, while the programming language stays the same — JavaScript. This alone can save you a significant amount of time and money, and this also means that your dedicated front-end JavaScript engineers can, in a pinch, help out on the back-end as well.


PHP is a general-purpose, server-side scripting language, the relative simplicity and versatility of which, at the time, has arguably been one of the main reasons for the boom of web development as we know it today.

First appearing in 1994, PHP — recursively short for PHP: Hypertext Preprocessor — now powers innumerable websites, from the smallest blogs to some of the most popular web services in the world.

While, once upon a time, PHP may have been criticized by some programmers, the current version (stable version 7.1.4) has an incredible improvement over those times, and PHP has grown into a language that can easily compete with others, like Javascript or Ruby, for back-end supremacy. Its frameworks provide good front-end support as well.

PHP was originally used embedded in HTML, but, nowadays, it is mostly used in the form of (frameworks)[#popular-frameworks]. It is the 4th most active repository programming language on Github, trailing only Javascript, Java, and Python, and, as such, it offers a very wide selection of pre-made libraries you might need for your project. The most important players, however, are PHP Frameworks like Wordpress, Symfony, and Laravel.


Python is a programming language first released in 1991. It is an interpreted language, which emphasizes code readability with a rather unique (among mainstream languages) approach of using whitespace delimitation of code blocks.

Python is a language which can be used on many platforms and its reference implementation, CPython, is open-source software, manged by the non-profit Python Software Foundation.

Being general-purpose programming language, Python can be used for a diverse array of tasks, two of the most common ones being web development and data science. With its long history comes an impressive list of success stories and a community that is always ready to extend a helping hand.


Ruby is an open-source programming language with a focus on simplicity and productivity. It was created as a blend of several other programming languages, with the goal of creating a language balanced between functional and imperative programming paradigms.

It was first publicly released in 1995 and gained wide-spread acceptance in 2006. It has consistently been ranked in the top 10 programming languages worldwide, much of which is due to its web framework Ruby on Rails.

Ruby has several implementations. Besides the reference implementation — MRI, Matz's Ruby Interpreter — there is also JRuby, which runs atop the Java Virtual Machine, MacRuby for the Objective-C Runtime, IronRuby, which is tightly integrated with the .NET Framework, and others. It is thus a very versatile language, but its most widespread use is on the web with the Ruby on Rails framework.


Go a.k.a. golang is a language created in 2007 at Google, and it was open-sourced in 2009. It is compiled, statically typed, fully garbage-collected, has limited structural typing, memory safety and concurrent programming features.

Go is an attempt to combine the ease of programming of an interpreted, dynamically typed language with the efficiency and safety of a statically typed, compiled language. It also aims to be modern, with support for networked and multicore computing. In every respect the language was designed by thinking about what programmers do and how to make programming, at least the kind of programming we do, more effective, which means more fun.

Go is one of those languages that have not been based on theory as much as on practical, real-life applications in cloud, system, distributed, and concurrent environments. It is a language for rapid development without sacrificing performance, which is actually comparable to that offered by C/C++. Unlike the latter, golang has very limited features, which does not reduce productivity, however, as most every programming concept can still be expressed.

Golang has been created with a focus on improving on several points of other languages, most notably shortcomings in dependancy management, type systems, memory management, and parallel computation and multi-core support, while it also requires less code for the same results as C or C++, due to its high level of expressiveness.

One of the primary use cases for golang is highly-performant, networked applications. Thus, it is perfectly suited for all sorts of back-ends for web and mobile applications. Especially when major scaling is expected and every millisecond counts, Go is certainly one of the best at its job.
