Frequently Asked Questions

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

A backend developer focuses on the 'server side' of an application: the server, database, and business logic that the user doesn't see. A frontend developer works on the 'client side', the user interface (UI) and user experience (UX)—everything the user sees and interacts with in the browser.

Do I need to know DevOps to be a backend developer?

It's not strictly mandatory, but it is highly beneficial. DevOps knowledge, such as CI/CD, containerization (Docker), and orchestration (Kubernetes), is increasingly expected as it allows backend developers to have more autonomy and control over the application lifecycle, from development to production.
