What is a Full Stack Engineer (SaaS)?

A Full Stack Engineer is an engineer who can work on both the front end and back end of a web application. A Full Stack Engineer is a web developer who is able to work on all parts of a web application including the back end, front end, and everything in between.The term "full stack" comes from the fact that these engineers are able to work on all parts of the "stack" which refers to the different layers of a web application. These layers include the database, the server, the web application, and the client side code. A Full Stack Engineer is someone who is comfortable working with all of these layers and can jump in and work on any part of the application.Full Stack Engineers are in high demand because they are able to build web applications from start to finish. These engineers are rare because most developers specialize in either the front end or the back end. A Full Stack Engineer is someone who has a deep understanding of how all the pieces of a web application fit together.If you're looking to become a Full Stack Engineer, it's important to have a strong understanding of both the front end and back end development. You should also be comfortable with a variety of different programming languages and frameworks.
