What is a backend developer?

backend developer

A backend developer is a person who specializes in web development, as it is sometimes called. This is the person who is responsible for the back of the website. For its functional content, not for its visual component. If you want to do it, then you should probably consider the profession of a web developer.

We first need to know how websites work in order to properly understand the role of the backend developer. Site code can be processed in two places: on the server side and on the client side.

Client-side programming is a place of work for front-end developers. They create the structure of a web page using HTML, CSS and JavaScript, smooth transitions, and make buttons interactive and editable with text boxes.

But all this will not work without server-side code work. The work is complex and requires you to be responsible for critical parts of the site. On the other hand, the backend developer turns out to be higher than the national average in most countries and even in the field of web development in general.

If you decide to register with BitDegree, you click the Register button. The website then redirects you to the registration page, where you enter your details and continue the process.

The backend developer sets up the work and checks how best to save your account details, makes sure they are correct (valid email address and confirmation email confirming that the address is indeed yours), and prompts for the appropriate information (username and password) when you enter next time.

When you browse our course pages, you will see buttons that will allow you to enroll in a course if you are not registered yet. When you click this button, the front end developers of the code call a function written by our staff to enroll you in the course.

Basically, the developer BitDegree wrote all the functionality that goes into running a website on the server side, while the interface wizards make the website look pretty and link the elements that you see as functional on the server side.

What is the backend developer responsible for?
Hopefully you now know a little about what a backend developer is and how it works differently from what a frontend developer does. But what is the backend developer responsible for?

Server logic
The best way to answer the question “Who is a backend developer?” is to say what the developer is responsible for in programming the server-side actions of the website.

Your area of ​​responsibility:

User authentication. Verify that the user’s account details are correct, that they have permission to access information, etc.
Processing orders. How your order is processed on the site without errors.
Optimization. Verify that all the functionality of the website not only works, but also works as quickly as possible.
Automatic notifications
They say that if you need to perform the same task multiple times, you must find a way to automate it. This is also true for how the website works. So what is the backend developer responsible for?

For example, when you register for an account with BitDegree, you receive an automated email to verify your address. This happens when you try to recover your password or perform any other action.

Where does the backend developer fit into the automation scheme? He is the person who writes the code that makes this process work. Imagine what would happen if thousands of users were online 24/7 and we had to manually send emails. You will have to wait several days for a simple email check.

There are also automatic notifications on the site informing you about new features and offering services that may interest you. The backend developer is also responsible for this.

Data checking
Besides programming the logic on the server side, the web developer is responsible for security. The portion of the website that you see in the interface can be modified in the browser by editing the HTML and CSS you see (F12 in Google Chrome). These changes persist until you reload the page.

If the entire site were so easy to change, online banking and even BitDegree would be impossible and extremely vulnerable. Fortunately, this is not the case, otherwise the whole world would be in trouble.

All the data you can imagine is stored in databases. When your browser generates the page you are about to visit, it retrieves the data values ​​it needs, such as prices, stock quantities, etc., from the database. When you enter information, you are prompted to update the database.

Where is the backend developer here? This poor fellow creates processes that validate the entered data before performing server-side settings.

The simplest case to show you how this process works is with a simple login procedure.

Let’s say you enter this email address: someguysemail@someemailprov.com with the password: $ uPer $ eurr £ a $$ 512.
When you click the Login button, this action triggers a request to verify the existence of an account with the email address someguysemail@someemailprov.com. If you have an account with this email address, but the password you recorded does not match the one you entered, you will also receive an error message.

In simple terms, any information you enter on a website must be validated by code written by a backend developer before it becomes part of the database.
