Full Stack Development is the practice of creating the front end and back end of websites and applications together. This type of code-based process creates websites that are not only efficient, but have rich visuals, interactive features, and specialized user experiences. The developers who specialize in this method are called Full Stack Developers, and they are the experts who create real-world solutions that clients need.

A Full Stack Developer is proficient in both the front-end and back-end of Application Development.
