A full-stack developer is someone with the ability to work on all “layers” of software development.

The three layers of a standard web application are:

  • Presentation layer.
  • Business layer.
  • Database layer.

Although full-stack developers are usually capable of working with each layer, they’re not necessarily experts on any one in particular.

Generally, the main areas a full-stack developer focuses on are divided into two: Front-End Development and Back-End Development.

Front-End Development

Front-End development (or web/app design) is focused on the Presentation layer i.e. the user interfaces.

The basic stack of front-end development includes:

  • HTML
  • CSS
  • JavaScript

Usually front-end developers will also work with frameworks / languages such as React and Angular to add further functionality on top of JavaScript.
