The freelance back-end developer, he/she is mostly active in the background and does not always stand out, but is an unmissable workforce in the digitalization of the business world. Every company is faced with the lightning pace of technology. Because of these technological advances and the huge shortage of developers, it is not always easy for companies to find the suitable workforce. Therefore, it is important to know what skills a back-end developer has and what you should look for.

What is back-end?

Back-end is seen as everything that happens behind the scenes of a Web site, application or program. In a site, for example, this might include registering new users, placing online orders or uploading videos, images or other files. This hidden process makes the front-end, what the user does see, work. In other words, the functions someone uses on the "front-end" are programmed into the "back-end. This back-end consists of three parts, namely the database, the server and the application itself. The front-end transmits data from the application or Web site to the back-end, which stores it in the database.

What does being a back-end developer entail?

The tasks of a back-end developer, or back-end programmer can be quite varied. First, their main job is to write out code that takes care of database interaction. The code helps the browser communicate with databases and process data, among other things. This coding is done using a programming language. Often, back-end developers specialize in a particular programming language. This is why they are often referred to as PHP, Python or Java developers, for example. Some of their duties include designing and maintaining applications, debugging to collecting and analyzing data. Finally, improving data architecture is an important aspect of the job package. This involves looking for patterns in data in order to make the software function optimally.

What skills does a freelance back-end developer need?

1. Extensive knowledge of programming language

An in-depth knowledge of programming is obviously essential as a freelance back-end developer. As mentioned earlier, back-end developers often specialize in a specific programming language or scripting language. A programming language lets computers perform large tasks. Unlike scripting languages that are used for small, common tasks. Below we give you an overview of the most used and popular programming and scripting languages among freelance back-end developers.

  • Python: A first important and most widely used programming language is Python. Especially its ease of use and the offer of extensive libraries for back-end development attract many developers. On top of that, Python's syntax is easy to understand compared to other back-end programming languages.
  • Java: Another very popular and coveted programming language by developers is Java. Java boasts considerable ease of use, numerous features and high security. As such, it has been called the mother tongue among all programming languages.
  • Javascript: Next, Javascript is a scripting language used to develop interactive Web applications. Javascript for back-end specifically can process payments and store users' messages, among other things.

  • PHP (Hypertext Preprocessor): Last, PHP is a scripting language that is especially important for developing dynamic Web pages and Web development.

2. Thorough knowledge of databases and servers.

A freelance back-end developer with analytical thinking skills is already very interesting for your company! In the database all data and website content is stored. As a developer you need to have a good understanding of different databases in order to analyze and interpret the amount of information. With databases, we can distinguish between two types, namely SQL and NoSQL. A SQL database represents data in tables, each of which is linked to another in a significant way. In NoSQL databases, on the other hand, data need not be structured in advance. Finally, the server refers to the computer system that receives a request from the site and on which the database runs.

3. Broad knowledge of APIs (Application Programming Interface).

An API enables communication between two different clients, software or services across the Internet. APIs receive a request from the client or user and send it to the server. The server then sends a response back to the client or user.
