Backend

Backend refers to the server-side systems that power a website’s functionality and handle data processing. When a user logs in, submits a form, or requests information, the backend receives the request, applies business logic, reads or writes data in a database, and returns a response to the frontend. Backend development also covers security controls such as authentication and permissions, along with integrations to third-party services like payment providers, CRMs, or email platforms. A reliable backend is essential for performance and stability, especially as traffic grows. Without a backend, a website is usually limited to static pages with minimal interaction.
