Back End

Let’s start by reminding the difference between back end and front end. To simplify, the front end is the part manipulated by the user, while the back end gathers all the technical and functional aspects necessary for the operation of a website or an application.

Specifically, the back end includes a server, on which is hosted a website which interacts with a database.


The back end developer has a lot of missions. Depending on the targeted website (institutional, e-commerce, employment etc.), he will issue recommendations on the choice of architecture : creation from scratch, or use of an existing framework or CMS solution (Content Management System).

Then, he will work on the development of the various technical features and test them in an acceptance testing environment. He will also configure the production server, realize the switchover from the acceptance testing server and ensure the technical support and maintenance parts during the entire life of the website.
