An application or web service can be divided into two parts: Front-end and Back-end . Their roles can be guessed from these names. The front end is the part you can "see". It is the part that lets you interact with an application or service. Colors, animations, layouts, and all the other cool stuff that adds to your experience of using an app or website is the front-end. The front end is often called the user interface (UI). The backend is the part you don't see. It is the inner workings of the application or website. This includes servers, databases, etc.

Some of the things a backend developer handles include:

1. Writing server-side code

2. Write code that interacts with the database

3. Ensure that the server-side code is secure and has no vulnerabilities
