Developers who specialize in both the front-end and back-end of websites and applications are known as full-stack developers. The software developers have a wide range of knowledge and skills, which allows them to implement solutions at every level of the system (view, business logic, database). All aspects of the assigned project must be handled by full-stack developers, from design to implementation to release. An experienced full-stack developer is indispensable in small and medium projects where cost is a significant factor.
