Top Skills a Backend Developer Must Need in 2021

When we hear about development, there are two types of development. One is front-end development and another is backend development. Here, we will discuss backend development and the skills a backend developer needs in 2021. 

When you want to fill a form on a website, you fill the form and press the button in order to take a demo class. Did you ever think about the procedure? What is happening behind the scenes? Where has your information gone?  You make solutions to these types of questions when you talk about backend web development.

Back-end developers are fewer in the world but they are worthy. If you want to work in this field, you have to learn a few key skills. But have no fear: if you’ve ever gone backstage to get a clear look at what goes on behind a show’s curtain or glanced beneath the hood of your car for the pleasure of it, you already have the curiosity that drives back end developers. You might be able to leverage your inherent passion to construct a meaningful job with little work and training. But it all relies on learning the necessary back-end development abilities. In this article, I will discuss the top skills a backend developer must need to be a part of the modern world. So, Let’s discuss each in detail.

What Does a Back-end Developer Do? 

Before we go deeper into backend development, first we need to understand what does a backend developer do? Front-end developers control the UI of the website— Design, Features, and CTAs. While backend developers perform the action on the run time. They alter code during the execution of the programs. The actions behind the scene are difficult to understand for an ordinary person. 

It is the responsibility of a back-end developer to ensure that a program can supply any needed data or information when a user makes a request to the system through a front end (i.e., consumer-side) framework. These programmers have additional responsibilities as well. They keep databases up-to-date, control (APIs), and test and remove bugs in back-end processes to guarantee that a program runs smoothly and efficiently at all times.

Sounds difficult? Surely it is. But once you step into it, you always get interesting things to do. You have to take interest in it and then it will be easy for you to become a back-end developer. 

Let’s talk about each skill of back-end developers in detail.

Top Skills of a Back-end Developer And How To Learn Them

There are millions of students who passed their graduation in Computer Sciences but not all learn the development. There are a few of them who jumps in the right direction. Unfortunately, everyone is not succeeded in this field because of its complexity. There are many back-end languages in the development field but if anyone has command of one language, he/she can be a good back-end developer. Python, Java, PHP, SQL, NoSQL, and Git are some of the major back-end languages trending nowadays.

  • Python

It has nothing to do with the snake that inspired this language name, but it is the most trending back-end language. If you want to jump into Python development, you need to learn its basics. According to a survey conducted by Stack Overflow in 2019, python is the fastest-growing development language in the world after Java.

In 2018, It is noted that 90,000 python developers respondents had told that they have used Python in their projects. It gain much popularity in the world because of its flexibility. It handles simple as well as complex projects with similar infrastructure. The reason is clear behind its success is the multiple programming styles and fantastic data visualization. The most famous websites— Spotify, Instagram, Disqus, Dropbox— are built on the Python Syntax.

Python’s reputation comes from the fact that it supports a variety of programming styles and produces outstanding graphical representations. Python gives the opportunity to programmers to use procedural, functional, and object-oriented programming techniques easily. The language’s capability for large data libraries streamlines display and speeds up development. Python is also relatively simple to learn.

  • Java

It is a wrong myth that Java is Javascript. First of all, remove this concept from your mind. These are two different languages and their procedure, functions, and characteristics are different from each other.

Java is the back-end programming language while javascript is used to incorporate animations and interactivity of the website. Both can run on different platforms and servers.

Java is primarily used for back-end programming. Java is often created in an Integrated Development Environment (IDE) before being compiled into bytecode, or low-level code that can be read by a software interpreter rather than human developers, making it a more reliable system. A JavaScript engine, on the other hand, can usually run JavaScript in its original syntax.  Java, in general, can handle more demanding programming jobs than its front-end counterpart.

  • PHP

It is the most inventive programming language in the world. According to Guru99, PHP has been used to create more than 20 million websites and applications. This is due to the fact that PHP is inviting, has a low level of difficulty, and is cost-effective because most web hosting servers support it by default. It also comes with built-in support for MySQL, a popular relational database.

While knowing PHP may not be a necessary ability for back-end developers who are familiar with other main programming languages, knowing it will make an aspiring programmer more employable.

  • Structured Query Language (SQL)

Technology may be outdated but SQL will always be prominent in the database industry. SQL empowers backend developers to manipulate RDBMS. In SQL, you perform different operations— Insert, Delete, Create table, OR, And, As, etc. You write different queries to perform different actions. You can also use MYSQL if you want to get more information about SQL.

The term NoSQL is used to store information rather than relational tables in the database management system. You can use SQL and NoSQL according to the client’s needs.


There are millions of agencies working on the internet to give better website development services. Everyone has their own expertise and experiences. In the above section, I have discussed the jobs and characteristics of a back-end developer. Back-end development is commonly used for alteration of the website at the run time. For Example: when you see a cricket match, the stats go upward and downward continuously. Back-end development is being used there and stats are changed at the run time.

Back-end development contains many languages PHP, Java, Python, SQL, NoSQL, Ruby, Oracle, and many others. They are in the same zone but they perform different functions and have different characteristics. The best practice to learn the back-end programming languages is to learn them one by one. When you have command of one language then move to the other. You can also learn these languages by online resources on the internet. 

I hope this article will help you to learn more about back-end programming languages and skills. If you have any questions regarding this, you can contact different back-end developers for further information.
