There are three types of programmers in web development: back-end developers, front-end developers, and full-stack developers (which work on both front-end and back-end). If you're reading this article, you're probably interested in the backend of your website, what the backend is, what the backend developer is, and how to become a backend developer. You want to know.




There are three types of programmers in web development, which are back end developer, front end developer, and full-stack developer (works in both front end and back end). If you are reading this guide, you are probably interested in the backend of a website and what it is as well as the meaning of backend developer and how to be a backend developer.

What is a backend developer?

Let’s find out what a Backend developer is. The backend developer is a web back end development expert. If you are just interested in how everything works, not the form of a website, and how to resolve complicated problems, why don't you find out how to become a backend developer with this tutorial?

First of all, we need to examine how webs work to interpret the role of a back-end developer. There are two places where code works to help everything go smoothly: the client-side and the server-side.

Client-side coding is a front end developer’s job. They create the web’s structures by HTML, CSS, and JavaScript for smoothing conversion, pushing the buttons and editable text.

Devwork is a point of view.

When deciding to sign up for Devwork, click the Sign-up button. Next, the website will navigate you to the resignation page, where you enter personal information and continue to process.

Backend developers will find the best way to store your account data, verify the accurate (a valid email address and the confirmation email address that is indeed you), and related information (username and password) when you sign in next time.

When you see the tutorial, you will see all the buttons that allow you to register for the courses. When clicking, code which front end developers write to call the function is written by backend developers that allow you to register for the courses.

Basically, backend developers in Devwork write all the functions working on the website on the server-side, while UI will make the website nice and connect all the functions. At this point, I hope that you have understood what the backend and backend developer is, haven't you? 

Backend developers’ tasks

Having interpreted the backend developers and what is the difference between their job and front end developers’, what are the backend developers’ tasks?

Server-side logic

The best way to respond when being asked “what is a backend developer ?” is a developer who is responsible for programming activities that webs perform on the server-side.

The main task will be:


  • Authenticate user. Ensure all the user account data is accurate that they have permission to access what is about to see, and so on.
  • Sequence control. How the sequences performed on the website are handled to ensure that there are not any errors.
  • Optimization. Make sure that every functional part of the website not only works but also works in the fastest possible way.

Automatic notifications

When you have to perform a recurring action, find a way to automate it. This is absolutely true for developing the web and exactly is one of the methods to answer the question “What are the backend developers’ tasks?” 

For instance, when registering an account in Devwork, you will receive an automatic email to verify your email address. The same happens when you try to recover a password or perform other maintenance tasks.

What is the role of the backend developer in the larger overview of automation? They are the one who writes the code that makes progress work. Imagine what will happen if there are thousands of users online 24/7 and manually send emails. You will have to wait several days to receive a simple confirmation email.

Meanwhile, there are also automatic notifications in place, notifying you of new features and service offers that may be of interest. All of this is done by the back end developers.

Verify data

Besides coding server-side logic, another answer to the question “What is the backend developer?” also is a system protector. Part of the web page visible in the front end can be changed in the browser by editing the HTML and CSS you see when inspecting (F12 on Google Chrome). Those changes will be maintained until the page reloads.

If the entire website is susceptible to this change, online banking and even Devwork will be extremely vulnerable. Thankfully, it doesn't work like that, or the world will be in trouble.

All the data you imagine a website need is stored data. When the browser creates the page you will view, it retrieves the necessary data values, like price, the quantity of items in stock, etc., from the database.

The simplest case of a process operation is a simple login procedure. 

For example, you enter this email address: someguysemail@mail.com with a password: $uP$rr£ 512.

When entering, this action will activate the request to see if there is an account with an email from someguysemail@mail.com. If not, you will receive an incorrect login message. If there is an account with this email address but the recorded password doesn’t match what you enter, you also will receive an incorrect login message.

To put it simply, any information entering the website needs to be verified by a code that was written by a backend developer before becoming a part of the database.

Access the database

Even though it is similar to the previous task, it still needs detachment to understand more. Backend developers’ job is to access the various databases maintained by the website to get the system to do what is required. You and code are the key to the failure or the success in ensuring the website is safe and working as intended.

Otherwise, it is your responsibility to streamline the database so the website loads and functions as quickly as possible.


Some people need a third-party API (Application Programming Interface) to work probably.  What is a backend developer? It is a person who ensures everything goes smoothly. You also can code API for other websites to use your web’s functions.

Working with API and creating it can be a large part of web backend development’s job, therefore, it is a good opportunity for you to be familiar with it. If lucky, it can be interesting when working as helping save a lot of time. Yet, it can also be quite a headache to split when coding a complex system from scratch.

Tools to develop backend

In terms of how to find out what a Backend developer is, it's nice to be able to know everything we have discussed above. You need to know what a Backend developer is, do not assume any tasks, and what jobs are involved.

However, it doesn’t help you to become a real backend developer. What is a backend developer? It is a person who knows those following tools:

Server-side language

While it is necessary to know the basics of HTML and CSS as a backend web developer, much of the work will be done in actual programming languages. PHP, Node.js (allows JavaScript for back-end programming), Python, and others can all be used for server-side coding but it's important to know which language to choose.

The problem is that different employers will be required to know different languages. You can't start working in a company that uses Node.js to enable JavaScript as a server-side programming language if you only know PHP.

Let's take a detailed look at the 3 most popular server-side programming languages below, in no particular order:


This programming language has been around for a long time but it shows signs of slowly being phased out. Although PHP can do a lot of great things, programming language critics say it has a messy structure.

Understandably, PHP wasn’t created as a complete programming language. The creator didn't even start as an appropriate programming language. Gradually, more and more people have used PHP and started adding which leads to inconsistencies.


When people hear about Node.js and what it is used for, people often get confused. For a long time, JavaScript was considered the divine programming language for the front end, but you needed to use an appropriate language to code the backend. With the advent of Node.js, that is no longer a problem.

Technically speaking, Node.js is not a programming language, it is a runtime environment that allows you to use JavaScript for server-side applications.

Since last year, there are still more opportunities for PHP developers than Node.js. However, now that the demand for PHP tends to decrease, perhaps Node.js will increase.


In fact, JavaScript can be used for server-side programming, which is why you should learn the language. Learning Node.js is the first backend development tool that can help you support yourself while getting ready to work at a serious company.

So how?

Even if you are planning to specialize in backend development, you will still need to master HTML, CSS, and JavaScript to understand how the front end works. If you focus on Node.js, you should be able to step into front end programming to become a website designer. In fact, customers won't care what you don't know if the simple website you create for them still works well and looks great.


Python is one of the most popular programming languages in the world, although at the moment it's used for machine learning purposes instead of back end development. Having said before, it's a good language, learner-friendly, comfortable to work with, and incredibly helpful.

The greatest strength in Python's ability to handle huge amounts of data. If you want to work on projects with big data applications, Python will be your best choice.

If you want to learn machine learning, Python is also a great language to learn in case you decide not to become a back end web developer.
