What is a backend developer?

Definition: A backend developer develops the functionality and data that powers a website or application. This involves creating, maintaining, and updating the software architecture, data structure, and servers that store information and code that powers the system. 

In general, backend developers work on a wide range of projects, including building new features and functionality for apps, improving existing features, fixing bugs or performance issues, implementing security measures to protect sensitive data stored in the app's database, and working with other developers and stakeholders to ensure that the system is functioning as intended.

What does the backend developer do?

Backend developers create and maintain the entire backend of one system.

For example:

  1. Backend website developer:
  • Manages APIs and hosting environments
  • Writes and optimizes codes behind websites
  • Finds and fixes system bugs
  1. Backend software developer:
  • Finds the right cloud computing platforms
  • Understands Agile development methodology
  • Creates and configures Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS) applications
  • Designs and implements large scale systems and Service Oriented Architectures (SOA)

After opening the website, the server sends information to the computer and the information turns into a visible website page. Backend developers make that possible. 

The same happens when requests are made within any other software.

What is the difference between a frontend and a backend developer?

Frontend developers ensure that users can easily interact with the system. They produce everything visible to the user.

Backend developers use different programming languages than frontend developers and maintain the application, software, and database behind the website, which users can’t see
