Depends on the importance of the user interaction. If the project is user interaction heavy, then it's always better to start from the Frontend. Because in the successive iterations you can test that UI and make some tweaks and improvements.
But, if the project is about something with very few user interactions, like a reports view, or a streaming based project, then it makes sense to start from the Backend.
