A full stack developer is a software developer who has expertise in both front-end and back-end technologies used in web application development. This means that they have knowledge and experience in developing the user interface (UI), the server-side application logic, and the database layer of a web application.

Front-end technologies typically include HTML, CSS, JavaScript, and related frameworks such as React, Angular, and Vue.js. Back-end technologies include server-side programming languages such as Java, Python, Ruby, or PHP, as well as web frameworks such as Node.js, Flask, or Django.
