What Is Full Stack Web Development?

Full stack web development covers both sides of a web application — the frontend that users see and interact with, and the backend that powers the logic, data and integrations behind the scenes.

For businesses in the UK and USA, working with a full stack development agency means one team handles everything — from database architecture and API development to user interface design and cloud deployment.
