Step-by-step explanation:
Britt most likely works in back end web development. Back end developers focus on server-side technology, which power the functionalities of a website.
Their work involves databases, servers, and application logic, which are not visible to the end-users. The front end developers, on the other hand, work on the client side of web development, crafting the user interface and experience that are directly seen and interacted with by the website's visitors.
