A Backend Developer is responsible for managing the behind-the-scenes functionalities of a web application. From server logic to databases and APIs, they ensure everything works seamlessly while the user sees only the polished frontend.
Server: A system that hosts, processes, and delivers data to users or applications.
Database: A structured repository that stores, manages, and retrieves data like user profiles and settings.
API (Application Programming Interface): A digital translator that lets two programs communicate.
Authentication: The process of confirming the identity of a user.
Encryption: Securing information by converting it into an unreadable format using algorithms.
They manage routes, responses, and services that live on the server. Every time a user clicks a button, it’s the backend that decides what happens next.

They handle CRUD operations (Create, Read, Update, Delete) using systems like MySQL, PostgreSQL, and MongoDB.
They build and maintain APIs that act as bridges between the frontend interface and the backend logic.
They apply secure login protocols, token-based authorization, and data encryption to protect user information.
Through tools like caching, indexing, and asynchronous processing, they reduce server load and improve speed.
They work with various backend languages depending on the project’s architecture and business goals.
