Introduction to backend developer skills

Who is a Backend Developer?

Backend developers are the experts who build and maintain the mechanisms that process data and perform actions on websites. They create the APIs and web services that front-end developers use. They handle both the front-end integration and the server-side logic. Their prime duty is defining and maintaining the central database, ensuring it performs well and reacts quickly to requests.

A backend developer is like a sous chef to a backend engineer's chef. Together, they are responsible for doing whatever it takes for a perfect result. The backend developer concentrates on features or activities that enable software development while understanding the framework the backend engineer created.

Top 10 Backend Developer Skills

Knowledge of Backend Programming Language

Language is the foundation of the development field; thus, you must have a vast knowledge of it. A backend developer will construct a reliable framework, and the servers connected in the required manner. You can achieve the needed outputs and functionality if you are fluent in the backend programming languages. The three common languages used by large tech companies are Java, Python, and PHP.


Due to its portability and exceptional performance, Java is amongst the most robust coding languages and is utilized by many major IT organizations (including Google, Amazon, Facebook, and others). It is used to build highly functional applications and dynamic web pages. Backend Java developer skills are also one of the most sought-after.


Python is known for making the development process easy and simple, with limited code lines and minimum rules to follow as compared to other languages.

Python backend developer skills are crucial since they can be used to automate processes, analyze data, create websites, and so much more. Additionally, it supports a variety of programming paradigms, including functions and object-oriented programming.


Today, PHP drives more than 80% of websites and has been considered a valuable language for backend developers for quite some time. A primary reason is that PHP can automate tasks and make it more convenient for developers to execute other vital operations simultaneously.

Knowledge of PHP

It's essential to thoroughly understand popular frameworks once you have clarity regarding which language you'd want to focus on. Frameworks provide a definite way of doing things and make it easy to develop complex applications. You might think about working on a few specific frameworks as a backend developer.


NodeJS is an open-source, cost-free platform that facilitates an application's backend coding. If you don't already know, this framework runs on JavaScript and can operate on many operating systems. These include Linux and Windows, to name a few.


Another framework based on NodeJS is ExpressJS. Backend developers strongly recommend it due to its speed and deliverability. ExpressJS is one of the finest options for building APIs.


Django is a free, open-source, Python-based web framework that has gained much popularity among programmers. The best thing about Django is that it enables rapid app development with less code and time.

Data Structures and Algorithms

As a back-end developer, good knowledge of DSA is necessary to design optimized algorithms and efficiently solve problems. These include knowledge of data sorting, stacks, queues, lists, stacks, binary search, and hashcode implementations. You should be able to choose the most appropriate data structures to solve a given problem.

Version Control System

It is also referred to as the source control and is responsible for tracking changes in the codebase. The version control system records every change to a code in a distinct “version”. This helps protect source code when a developer messes up and wishes to undo it. Some of the most well-liked version control platforms for backend developers include:

  • AWS Code Commit: This is a different version of the control system that Amazon is hosting. A user can save and manage data with this and the source code. A Git repository is used to maintain this highly secure platform.
  • GitHub: It is an open-source forum created in 2007 to assist developers. Anyone accessing the cloud can read the code, and coders can collaborate and contribute however they see fit. Anyone anywhere can help those in need with the assistance of this community, and as a result of its widespread use, millions of users are currently connected to this platform.
  • GitLab: It enables users to collaborate and carry out all tasks on a single platform. Doing this aids in shortening the time and boosts output. In other words, it enables groups to create flawless software using a single communication channel.

Knowledge of API

The API, or Application Programming Interface, is responsible for setting up connections between various applications. For instance, you connect to Alibaba's API while placing an order for a product through the company's mobile application. Backend developers use these APIs to connect various applications and improve user experience. Developers frequently use JSON, GSON, SOAP, REST, and other standard APIs.

Knowledge of API

Databases and Cache

Database management systems, often known as DBMS, are how programmers stores and organize massive volumes of data generated by websites and apps in a structured and efficient way.

A few popular database management systems that backend engineers should be familiar with are PostgreSQL, AWS DynamoDB, and Oracle. These solutions are all used to manage massive amounts of data, but they also use caching for small data from individual users.

Server Handling

All backend development is server-side development, so understanding servers are crucial. A server is a system or computer that offers information, resources, and services to other computers or clients across a network, including file storage, security, and databases. The most well-known servers include Microsoft Windows Server, NGINX, and Apache. Knowing the fundamentals of Linux is also very beneficial because most such servers support Linux OS. Docker and Kubernetes are some of the leading server management solutions.


Backend development is a rewarding career choice for those who enjoy solving problems because it can sometimes be challenging. Since a backend developer often acts as a website's problem solver, curiosity and a desire to find solutions are crucial traits to possess when starting.

Communication and Interpersonal Skills

Although there are options for individual work in backend web dev, it's also critical to have strong, soft skills like effective communication and teamworking. To ensure a site operates at its best potential, backend developers frequently need to collaborate closely with front-end developers and a large team; therefore, effective communication is crucial.

Communication and Interpersonal Skills

Backend Developer Salary

A web developer's duties and responsibilities start with website design and end with efficient implementation and maintenance. Backend website developers with experience of one year or less are usually paid an annual package of Rs.241,239. The average total income for website developers with about four years of professional experience in their early career is ₹305,745.

The salary can later range to about Rs.850,000 per annum for backend developers who are skilled with Java backend developer skills and Python backend developer skills.

Along with the job's demand and location within the nation, several other criteria are considered when determining the ultimate wage. The following factors come into play:

  • Experience: A developer's pay will be based on years of work experience. A novice in the profession may have the talent, but an experienced individual may have a greater understanding of managing the circumstance due to their expertise.
  • Location: Given the cost of living factor, it is undeniable that urban areas have higher pay scales than rural areas.
