The user, blissfully unaware, thinks they're interacting with a beautiful frontend while the backend developer lurks behind the scenes making everything actually work. The frontend gets all the praise for being pretty, while the backend carries the entire application on its shoulders. Tale as old as time: users only care about what they can see, not the complex machinery keeping the whole operation from imploding. That backend developer's face says it all - "You're welcome for making this thing functional while the frontend gets all the credit."
