representing the individual components. The term "solution stack" has, historically, occasionally included hardware components as part of a final product, mixing both the hardware and software in layers of support. A full-stack developer is expected to be able to work in all the layers of the application ( front-end and back-end). A full-stack developer can be defined as a developer or an engineer who works with both the front and back end development of a website, web application or desktop application. This means they can lead platform builds that involve databases, user-facing websites, and working with clients during the planning phase of projects.
