Full stack software development is the process of designing, creating, testing, and maintaining a software application. The term full-stack refers to developers working in this field are expected to have a complete understanding of all software application layers. This includes the front-end (client-side) and back-end (server-side) as well as the database, network, and security layers. To be successful, full-stack developers must have a firm grasp of programming and systems administration.
The most common technology stacks for full stack software development are MEAN (MongoDB, Express, AngularJS, and Node.js), MERN (MongoDB, Express, React, and Node.js), and LAMP (Linux, Apache, MySQL, and PHP). Each stack has its strengths and weaknesses, but all three are popular choices for building modern web applications.
