Top 14 Skills for Backend Developer

Let’s look at some skills you should have as a backend engineer. You should work towards acquiring these must-have skills to crack backend developer interviews at the biggest tech companies.

1. Backend Programming Languages

Backend developers use multiple programming languages. The two main categories are:

a) OOP (Object-oriented Programming):

This organizes code into reusable class and object building blocks. Popular languages include Java, .NET, Python, etc.

b) Functional Programming:

Aims on mathematical functions, minimizing shared data. Languages like Clojure, Haskell, SQL, etc.

2. Database Knowledge

Every website requires a database to deal with client data. A database stores the data and website content in a way that makes it easy to recover, arrange, modify, and store data. 

Two types of databases available in the market are:

a) SQL: A SQL database is one where the data is tabulated in a table, and each is linked. They work on queries and produce results depending on them. Example: PostgreSQL, MySQL.
b) NoSQL: Here, there’s no need to structure the data beforehand. NoSQL databases work basically on JSON and XML. Example: Cassandra, MongoDB.

3. API Knowledge

Application Programming Interfaces facilitate software communication while helping various systems talk to each other, using HTTP methods like GET, POST, PUT, and DELETE. Backend developers create APIs to fetch user data, improving user experience.

4. Cyber Security Awareness

With the growing number of cyber threats, backend developers must prioritize security. Knowledge of the best practices for securing web apps, knowing common vulnerabilities, and implementing appropriate authentication and authorization mechanisms are necessary.

5. Knowledge of Servers

Each web application runs a remote PC known as a server. The rem server commonly refers to the computer system that requests web-based files, including HTML, CSS, Javascript, etc., and forwards those files to the client.

Servers are the commonly used channel to deliver essential pieces of information; most servers are never turned off. This part of the servers makes it necessary for a backend developer to know about it. Examples: IIS Servers, Apache, Microsoft IIS, Nginx.

6. Frontend Technology Knowledge

In the world of backend technology, a touch of frontend knowledge significantly elevates your capabilities. Knowing the fundamental frontend web development technology languages like HTML, CSS, and Javascript is a must, as they give you the power to communicate with the computers, instruct them, and create engaging user experiences. Enroll in an online Frontend Development Course and get hired by top MNCs.

7. Backend Frameworks Knowledge

Along with choosing a type of programming language, you must embrace its ecosystem with backend frameworks. These frameworks streamline your development process, giving ready-to-use tools and libraries. 

Below are a few standout options:

a) Ruby on Rails:

This open-source framework, written in Ruby, crafts seamless web apps and is packed with automated testing, libraries, and scaffolding. It’s your ticket to efficient localization.

b) Node.js:

An open-source platform for back-end development. With Javascript at its center, it’s a maestro framework that’s cross-platform and compatible with Linux, Windows, and macOS.

c) Express.js:


Built on the blocks of Node.js. Its glaring speed and reliability make it a favorite among backend developers. It is ideal for APIs, and it shines in crafting web and mobile applications.

d) Django:

An open-source gem that has captured the developer’s heart. Django’s magic lies in its nominal code requirements and rapid app development prowess. 

e) Flask:


A Python-based framework for present-day creations. From WSGI assistance to quick templating, it boasts an in-built development server.

8. Version Control System

With code’s evolution, version control systems become invaluable. These systems track code changes, making reverting to previous versions and safeguarding your source code easier. 

Below are some noteworthy systems:

a) AWS Code Commit: Amazon’s secure version control system is perfect for managing source code and data.

b) GitHub: A famous open-source community repository that fosters collaboration and contribution among developers.

c) GitLab: A comprehensive platform that enables collaboration and efficient software development through streamlined communication.

FAQs on Backend Developer Skills

1. What is the difference between frontend and backend development?

The frontend is the user-facing part, while the backend is the server-side. Both are crucial, but their roles, responsibilities, and work environments differ. The front end is what users see, while the back-end is the engine that powers everything behind the scenes.

2. What should I learn to become a backend developer?

Back-end developers should know at least one backend and server-side programming language. They must also learn how to create, read, update, and delete (CRUD operations) data from a database and transmit it to the user-facing side of the server. Back-end developers must be proficient in handling APIs, HTTP protocols, and version control systems like Git.

3. Why is problem-solving a critical skill for a backend developer?

Mastering problem-solving is not just a skill but a necessity for backend developers. They often encounter intricate issues, such as optimizing database queries and ensuring data security. The ability to solve these problems efficiently leads to reliable solutions.

4. How do backend developers collaborate with other team members, and why are communication skills necessary?

Backend developers work closely with frontend developers, designers, and project managers. Effective communication and interpersonal skills are vital so that everyone is aligned on project timelines, objectives, and requirements, facilitating seamless teamwork.

5. Is DSA required for backend developers?

A solid understanding of DSA can be beneficial, but it’s only sometimes necessary for every backend development role. However, grasping basic data structures like arrays, linked lists, stacks, and queues and knowing how to use algorithms like sorting and searching can undoubtedly give you a leg up when tackling programming problems.

6. What type of back-end developer interview questions are asked in technical interviews?

Back-end developer interview questions mainly focus on core DSA concepts like arrays, strings, linked lists, recursion, tables, graphs, and trees, and core design concepts such as databases, network protocols, sharding techniques, loading, caching, file systems, online processing systems, and servers.
