The web is entirely powered by back end development. Additionally, back-end development works with the front-end to provide final results to the end users.

What Does a Backend Developer Do? Roles & Responsibilities

A back-end developer is accountable for creating and designing the infrastructure of websites. As we discussed back end development, now let’s understand backend developer roles and responsibilities.

1. Writing Top-Notch Code 

One of the critical responsibilities of back-end programmers is writing easily manageable and clean code to develop web applications ideally. 

2. Creating and Maintaining Websites 

Another critical responsibility of a back-end developer is determining how ideally to create user-friendly, intuitive prototypes and convert them into websites using multiple tools, languages, and frameworks. For this purpose, an understanding of cross-platform compatibility and functionality is crucial.

3. Doing Quality Assurance Testing Evaluating Speed and Efficiency

Back end programmers are also responsible for developing and overseeing the testing schedule to optimize user interface and experience, ensuring ideal display on various devices and browsers.

4. Offering Support and Training

Leading mentorship and training for subordinates, along with managing workflow with client teams to ensure advanced support, are also among the primary responsibilities of back-end developers.

5. Troubleshooting Issues

A backend engineer is also in charge of troubleshooting and resolving the problems while communicating them to stakeholders, project managers, and quality assurance teams.

Tools For Backend Development

There is a vast set of tools for back-end development in the tech world that makes the task easier for back-end developers. These tools prove beneficial in creating, testing, and maintaining website applications. These tools include programming languages, servers, databases, and frameworks.

1. Programming Languages

Programming languages used by back end engineers are C#, Ruby, Python, JavaScript, PHP, and Java. Let’s discuss the most important and widely used programming languages in detail.


One of the most preferred programming languages for back-end development is Python. It is a general-purpose and top-level programming language that supports various programming models such as functional, procedural, and object-oriented.

Some of the most famous examples of platforms using Python in their tech stacks are Google, Spotify, and Instagram. Python provides exceptional features, such as easy integration with other languages, rich library support, compatibility with trending technologies, GUI Programming support, etc.


The acronym of HyperText Preprocessor is PHP. It is a server-side scripting language widely used for back end development of websites. Various well-known websites that rely on PHP include Wikipedia, Facebook, WordPress, and others. 

The reasons behind the preference for PHP over other programming languages are OOP features, cross-platform compatibility, and easy integration with CSS, HTML, JavaScript, etc.


JavaScript is widely popular because of its substantial role in the development of websites. Alongside CSS and HTML, JavaScript is the basic unit of web development. The best part of JavaScript is that it can be utilized for both backend and frontend development.

2. Frameworks

Frameworks are another vital tool used by back end developers. Common frameworks include Laravel, Spring, Meteor, Django, Node.js, and Ruby on Rails. Although all these frameworks are used for website development, the most popular are explained below.


In the tech world, the most popular framework is Laravel. It is an open-source website framework based on the model view controller architectural pattern. It also offers multiple upgraded features like Template Engine, Eloquent ORM, and Modular libraries.


Another open-source website framework is Django, which lets you perform the task of website development more effectively. The architectural pattern followed by Django is a model template view. The features that make Django the most popular framework are its scalability, extensibility, security, fast development, and vast community.

3. Databases

Databases are also among the popular backend developer tools. Common databases are MongoDB, Oracle, and MySQL. 


One of the web developers’ most well-known databases is MongoDB, a free and open-source document-oriented database. Prominent features of MongoDB are aggregation, Indexing, Load Balancing, and Replication.


Another popular open-source relational database management system is MySQL, which is used explicitly for website applications. It offers better reliability, usability, and scalability. 

4. Servers

Servers are also backend tools for web development, among which the most common are Apache, Microsoft IIS, NGINX, and Lighttpd. However, NGINX and Apache are widely used among all the servers because of their user-friendly features.


NGINX server is commonly used for catching, load balancing, proxying, and mail proxying.

Most enriching features of NGINX are IPv6-compatible, handling static files & auto-indexing, URL rewriting & redirection, etc.


Apache is a leading open-source, cross-platform server, as approximately half of the total websites across the world are powered by Apache. Prominent features of Apache are CGI support, Loadable Dynamic Modules, User and Session tracking, and Multiple Request Processing modes.

Why is Backend Development Important?

Many reasons show the importance of backend development. The most apparent advantage of back end development is speed. Backend programmers can effectively and quickly produce apps because they deal with smaller codebases than front-end engineers.

Additionally, back end development is essential because it ensures the websites function accurately while focusing on the back-end logic, databases, servers, architecture, and application programming interface.

Backend Development Process

A back end platform has three leading roles, which are discussed below.

1. Acquiring Information that User Wants Through App 

While using an app, a user always requires data regardless of the product’s nature. This is true whether it is a scheduling app that lets the user set their daily schedules or a weight loss app where the user needs exercises and tips from the app to lose weight.

2. Combining and Transforming Gathered Information 

The data needed for an app to function correctly comes from databases. For this purpose, back-end developers find specific information from databases and combine all the valuable information to offer the best results to the users.

3. Giving Back Information to User

During the backend development process, the data is sent to the user once all the information is gathered and combined correctly. However, most users need to learn how to read the details in pure code produced by the back-end developers. For this purpose, translators are used by the back-end designers to translate pure code into human language and make it easy for users to get the information in the simplest form.

Key Skills to Look Out for When Hiring Backend Developers

Back end development is a complex process and requires in-depth understanding, expertise, and knowledge of specific skills. The essential skills to look out for while hiring backend programmers are discussed in detail here.

A back end engineer should also be skilled in databases, cache management, HTML, CSS, and JavaScript. Also, the familiarity of backend engineers with servers, APIs (XML and JSON), Version Control, and Version Control Systems (e.g., Git) can’t be ignored.

2. Problem-solving Skills

Along with technical skills, back end programmers should be experts in problem-solving skills because issues can occur anytime, so back-end developers must tackle the problems efficiently.

A skilled back end engineer possesses an in-depth understanding of the field and creativity, which makes it easy for them to solve problems.

3. Communication and Interpersonal Skills

Among the skills needed for backend developers are good communication and interpersonal skills. A back end engineer with good communication skills is a superb team player because, along with creating and maintaining the project, he also understands how to communicate effectively with teammates and customers to run the project smoothly.
