Backend Development

What is Backend Development?

  • Backend Development, also known as server-side development, encompasses everything that users don’t see directly but is essential for the functionality of a website or application. It involves managing databases, backend logic, APIs, and servers.
  • The backend of a website consists of servers, applications, and databases. Backend developers write code that enables browsers to communicate with databases, store and retrieve data, and handle various operations like data updates and deletions.

For example, when you submit your details on a website, the data is sent to a server, processed, and stored in a database. This entire process occurs behind the scenes, making it part of the backend.

Backend Developer’s Role

 A backend developer is responsible for

  • Building the structural foundation of software applications.
  • Collaborating with cross-functional teams, including frontend developers, designers, product managers, and testers.
  • Developing APIs to enable data communication.
  • Ensuring data security, user authentication, and access control.
  • Optimizing application performance and scalability.
  • Troubleshooting and debugging backend code.
