The backend is essentially the brains behind the face (the frontend).
A backend developer is therefore responsible for building and maintaining the technology needed to power the frontend, consisting of three parts: a server, an application and a database.
The code that backend developers create ensures that everything the frontend developer builds is fully functional, and it is the backend developer’s job to make sure that the server, application and database all communicate with each other.
Then they use tools like MySQL, DynamoDB, Postgres and MongoDB to find, save or edit data and deliver it back to the user in frontend code.
Just like frontend developers, backend developers will liaise with the client or business owner in order to understand their needs and requirements.
They will then deliver these in a number of ways depending on the specifics of the project.
Typical backend development tasks include creating, integrating and managing the database, building server-side software using backend frameworks, developing and deploying content management systems as well as working with web server technologies, API integration and operating systems.
Backend developers are also responsible for testing and debugging any backend elements of a system or application.
