full stack web developer

Full-stack developers are professionals who can work on both the front-end and back end of a website. They organize a website creation process from start to finish and therefore should know all the different aspects of making a website function.

If you’re interested in this hybrid specification, that’s great! As a full-stack developer, you will have a varied and exciting job with many responsibilities. But what languages should you learn to become a full-stack developer? This blog post will discuss the full-stack developer languages that every field specialist should know.

But first, let’s figure out:

Who is a full-stack developer?

Before jumping into the description of a full stack developer, make yourself familiar with the two main branches of website development.

A front-end developer is responsible for the look and feel of a website. Front-end specialists work on the visual elements, like the layout, colors, fonts, and images. In short, a front-end developer is responsible for the UI/UX of the website.

Back-end developers play in the background of the website. They work on the behind-the-scenes aspects, like user authentication, data storage, and other functionality. So, front-end developers give a human-friendly shape and look at what the back-end developers create. 

A full-stack developer is a hero who combines those two jobs. Unlike web designers, full-stack developers are responsible for the overall functionality of a website. They create websites from zero, working in all the separate components that make up a final digital entity.

What are the responsibilities of full-stack developers?

Well, full-stack developers do everything related to website construction. But this might be a too broad explanation; that’s why here is the detailed breakdown of the full-stack developer’s role. 

  • Creating the prototypes of websites in tight cooperation with user interface teams
  • Developing robust front end architecture for flawless user interactions 
  • Developing a powerful back-end for fetching data from servers
  • Conducting or controlling database and server administration duties
  • Ensuring a smooth running of the web product on all operating systems
  • Surveying end-users and testing the product to determine product effectiveness at the pre-launch state
  • Organizing the final launch of the product and controlling the fixing of bugs or any interruptions of the website.
