What is ‘Backend Developers’


The backbone of any website or application is the code written by the back-end developer. Find out what it takes to enter this sector of work. Have you ever been curious about the inner workings of a website?

But how does it work that when you click a button it takes you to a new page? When you join up for a free trial, what happens to the information you provide? Specialist “back-end” developers construct and manage the systems that carry out the tasks required to process data and operate websites.

Back-end developers work on the unseen server-side aspects of a website, such as data storage and security, while front-end developers manage the user interface. Web development has progressed significantly since the late 1980s and early 1990s, when the internet first became widely used.

Developers are in high demand since the web is essential to modern life. The good news is that the technical knowledge required to work as a front-end, back-end, or full-stack (both front- and back-end) developer is something that can be taught to anyone with a willingness to learn.

What is Back-End Development?

Back-end development refers to the process of creating the invisible parts of a website, or the server-side software. Website performance is monitored and maintained by back-end developers who work on the site’s databases, back-end logic, APIs, architecture, and servers.

Data is stored, interpreted, and deleted with the aid of code that facilitates communication between browsers and databases. Together with the front-end developer, product manager, lead architect, and website tester, the back-end developer creates the framework for a website or mobile app.

Programming languages like Python, Java, and Ruby are just a few of the many tools and frameworks that back-end engineers need to know. They guarantee the back end is speedy and responsive to the needs of the front end.

What Backend Tools do Developers Use?

These programmers, like all coders, have access to a vast array of hardware and software for use in doing their tasks. It’s no wonder that backend engineers have their preferred coding languages, given the complexity of working with databases and communicating across multiple pieces of computer infrastructure.

Also, keep in mind that they rely on a rarely-discussed tool: their interpersonal abilities. The server-side of an application relies on a number of tools and techniques, so let’s take a deeper look at what they are.

Popular Backend Programming Languages

For the backend of a website, developers often use Python, Java, PHP, and/or Ruby. Python is one of the most widely used languages in part because it works well with AI and machine learning.

In spite of its widespread use among data analysts and scientists, learning Python for web development has many benefits. You should also grasp the fundamentals of front-end languages like HTML, CSS, and JavaScript.

You should still familiarize yourself with the fundamentals of these front-end languages because your code will interact with them.

The front end of a website may be built using these three languages, and Career Foundry’s free 5-day coding short course will introduce you to them. As a means of familiarizing oneself with the front end before tackling the back end, it’s a useful tool.

Common Backend Technologies

To avoid having to re-invent the wheel, developers might make use of pre-existing libraries known as frameworks. Being a popular framework, Node.js facilitates the backend use of JavaScript. In order to get started with Node, I recommend checking out our primer.

Database Management Systems

The database is where all of your website’s client and customer information lives. If you want to be a backend developer, you need to know your way around databases and how to get the information you need.

Using both relational and non-relational databases, as well as the fundamentals, is recommended.

Data Structures and Algorithms

It’s possible that you’ll be in charge of establishing the organizational framework and logical organization of your company’s data. Same goes for figuring out how to best deal with requests for large amounts of data.

API design is another possible avenue here. Application programming interface (API) design is the method through which APIs (application programming interfaces) are created and made available to programmers and end users.

Version Control

Any competent backend developer should know their way around Git, GitHub, and the deployment pipeline. Tracking changes to your code is a breeze with Git, a version-control system. GitHub is a cloud hosting service that also offers a suite of collaborative tools for your team to use.

Web Hosting Platforms

That’s where your website “lives,” or is hosted. If you want your website to be accessible online, you’ll need to find a cloud service provider. Popular cloud service providers include Amazon Web Services (AWS), Google Cloud Platform (GCP), Microsoft Azure, and Heroic.


A backend developer’s duties may also include ensuring the safety of your servers and databases. There are a number of things you’ll need to do, such as securing your API routes and dealing with and verifying authentication whenever a user registers in or makes a data request.

Server-side development describes the work done on the back end of a system. All that goes on behind the scenes when a user performs an action on a website, unseen by the user.

Data storage, server-side processing, application programming interfaces, and back-end infrastructure are its primary concerns. Servers, programs, and data stores make up a website’s backend.

Data storage, retrieval, modification, and removal from databases are all facilitated by the code built by backend developers, which is used by browsers to interact with these systems.
