Profession_ Backend Developer

Are you considering entering the IT field or looking to switch careers as a developer? Becoming a Backend Developer is a great choice. Find out who they are, what they do, and how to become one in our article.

A Backend specialist will always be in demand wherever companies or individuals interact with their consumers or clients through websites or applications. With the clear trend of digitalization in most commercial sectors in recent years, a Backend Developer will remain in high demand for a long time. They are responsible for developing not only websites but also e-commerce platforms, banking services, marketplaces, product aggregators, and more.

Among the advantages of this profession are career growth, high salary, flexible work format, and the opportunity to work remotely for foreign companies.

What is the role of a Backend developer?

This is a specialist who is responsible for the backend or internal side of a project. They write code for the server, which handles processing, storage, and access to data. The quality of the backend code determines the proper functioning of all client applications and websites. Any flaw in the code can disrupt its operation.

Backend programming is relevant not only for web solutions or mobile applications but also for the industrial sector. In a broad sense, backend development is applied to any service that involves software and hardware components. Thus, a Backend Developer focuses on creating the part that users don’t see but that provides the core functions of the system.

Frontend Developer vs. Backend Developer: What’s The Difference?

The client side, which is what the user sees, including visual content and interactive user experience, is created by a Frontend developer. The internal part, Backend, ensures data management, handles the core logic, and retrieves the required information for further display and processing on the user interface (UI). In other words, Backend provides data to the Frontend, which the user interacts with. This is the main difference between these two components – frontend and backend. 

What Does a Backend Developer Do?

To enter this profession, it is necessary to have strong and well-developed hard skills. Depending on the level of expertise, a specialist should possess the following skills:

  • Knowledge of programming languages, one or more of the following: C#, Python, Java, PHP, C++, and others
  • Ability to work with databases, particularly with MsSql, MongoDB, PostgreSql, MySQL – including designing their structure and writing queries
  • Understanding the functionalities of servers such as Apache, IIS, NGINX, and others
  • Having an understanding of various data structures, their applications, and how to work with them
  • Knowing and applying sets of methods, libraries, classes, and functions from frameworks
  • Know the basics of Frontend (preferably but not necessarily)
  • Understand backend server architecture

The backend developer’s job is to:

  • Writing correct code for web applications and APIs
  • Designing databases
  • Ensuring server solutions are protected from unauthorized access, considering potential and known vulnerabilities
  • Testing the backend components of the project
  • Developing application architecture and logic.

Recent research indicates that Python is currently the most popular programming language. However, this doesn’t mean that other languages are less in demand. Here are some of the most sought-after and popular programming languages today:

  • JavaScript
  • C#
  • Java
  • PHP
  • Ruby
  • С++

For example, both Python and Java backend are suitable for various purposes, including developing the server-side of web services, mobile applications, corporate software, programs and services for the financial sector, and game development for computer and video games.

The uniqueness of backend development lies in the fact that the more complex the project, the greater the knowledge required. Developing a small online store may not demand extensive expertise, often requiring an understanding of HTML, PHP coding, and service operations. However, creating a large-scale marketplace or social network necessitates deep knowledge of microservices architecture, backend performance, proficiency in Scrum methodology, utilization of containerization technologies, and understanding of server monitoring systems, computer network services, and network equipment.

10 Best Backend Development Frameworks for 2023

A framework is a development environment that consists of libraries and pre-built solutions where developers write code. Frameworks are designed to simplify coding, make the process faster and more efficient, and enable developers to write high-quality code even without extensive experience. By providing ready-made components, frameworks reduce the time spent on writing code from scratch and allow developers to focus on the core functionality of their projects. There are both specific frameworks designed for one programming language and universal ones that can be used for programming in multiple languages.

Below, we have listed only a few of the existing frameworks:

  • Spring Framework + Spring boot for Java
  • Django for Python
  • Express.js, Nest for JavaScript
  • Laravel for PHP
  • ASP.NET core for .NET development
  • Flask Framework for Python
  • Ruby on Rails for Ruby
  • Fiber Framework for Golang
  • Play Framework for Scala and Java
