A LAMP stack developer specializes in the components of the LAMP stack, including Linux, Apache, MySQL, and PHP. A full-stack developer, on the other hand, has expertise in multiple technology stacks, including front-end and back-end development. While a LAMP stack developer may be able to create a complete web application, a full-stack developer can handle all aspects of web application development, including user interface design, server-side programming, and database management.
