Full-stack developer woman working on her laptop.

A Full-Stack Developer has the ability to work on both the front-end and back-end portions of an application, software, or website. However, Full-Stack Developers are considered to be “jacks of all trades” but not necessarily masters of all. These professionals typically have a holistic understanding of both the back-end and front-end technologies.

What does a Full-Stack Developer do, typically?

Full-Stack Developers have a range of skills and breadth of knowledge. These professionals’ experiences vary greatly and their skills and knowledge of technologies can vary as well.  Full-Stack Developers may work on projects that involve building applications, software, or websites. Generally, these developers should have a level of proficiency in the following categories and languages:

  1. HTML/CSS – allows you to add content to a website and style the content
  2. JavaScript – most popular language in full-stack, front-end, and back-end development
  3. One or more back-end (programming) languages such as:
    • SQL
    • Java
    • C#
    • C++
    • Python
    • PHP
    • Ruby
  4. REST & HTTP – Allows clients to communicate with servers
  5. Databases & web storage – Storing data to be accessed at a later time (MySQL, MongoDB, Oracle, etc.)
  6. Git/Github – Allows developers to keep track of all changes being made to a codebase (get the latest code, update parts of a code, make fixes, change code without breaking things)
  7. Basic understanding of design including:
    • UX
    • UI
    • Interaction
    • Front-end development (HTML, CSS, JS)

Full-Stack Developers are not:

Front-End Developers

Everything that is seen on a website (known as the front-end), was developed by a Front-End Developer. And, although Full-Stack Developers know at least some front-end technologies, they are not masters of Front-End code and processes. Front-End Developers are skilled in HTML/CSS, JavaScript frameworks, JQuery, and responsive design.

Back-End Developers

Back-End Developers are needed to make the server, application, and database communicate with each other. Back-end developers use server-side languages like PHP, Ruby, Python, Java, and .net to build an application, and tools like MySQL, Oracle, and SQL Server to find, save, or change data and serve it back to the user in front-end code. These developers specialize in the back-end of website, applications, and software. They are not typically skilled in the design elements of front-end or full-stack developers.

  • CPU
  • Time to Interaction
  • Interaction response time
  • Page rendering
  • DOM processing
