What is a full stack developer?

If you’ve been looking for information on how to become a programmer or web developer, you’ll surely have come across courses that prepare you to become a Full Stack Developer.

But what exactly is a Full Stack Developer?

At Ubiqum Code Academy, we want to explain the concept in detail and tell you how you can become one with our intensive coding bootcamps. A full stack developer, in any of the two modalities that we offer in Ubiqum, is a guarantee of high quality digital employment and is available to anyone with enough motivation to work hard for 500 or 800 hours intensively. Everyone can learn to program, we guarantee it.

Back to the question: a Full Stack Developer is a web and app developer with knowledge of all facets of front-end and back-end development and project management tools. The frontend refers to what your users see, and the backend deals with all those behind-the-scenes processes like databases, integrations, and security.

What does a Full Stack Developer need to know?

  • Frontend: the frontend of an application is the part that interacts with the user. If you think of the application you use to communicate with your bank from your cell phone, the frontend is the part that you have loaded on your device and use from there. The frontend, beyond web programming, must consider the usability, design, structure and readability of the app. The frontend must provide a satisfactory user experience that invites to repeat.
  • Backend: In contrast, the backend is the part that runs on the server and is invisible to the user. If you think of your bank’s application, the backend is where your token is, which identifies you as a user and your account balance information.

What does a Full Stack Developer do?

To work as a web developer on both the backend and frontend of a web or mobile application, a Full Stack Developer must have good knowledge of the following subjects:

Front-end programming tools and languages


HyperText Markup Language, specifically HTML5, is the basic language of the World Wide Web. HTML5 is a markup language and is not strictly speaking a programming language, since it has no logical functions. It is a way of coding a document that, along with the text, incorporates tags or markup containing additional information about structure and how text is presented in the browser. In short, it displays app or website content and ensures it is consistent in its style.


Cascading Style Sheets is a language that inspires the design of a structured document written in HTML. The idea behind the development of CSS is to separate the structure of a document from the more arty side. It is as important as HTML5 in being one of the fundamental building blocks of any app or website. CSS is used to create style sheets that give shape and design to the content created with HTML when viewed in the browser. The most common version in today’s business environment is CSS3.


JavaScript is the programming language that gives life to the elements of an application. Think videos, animations, and responsive layouts — JavaScript helps you go from boring fixed pages to dynamic, interactive apps. Interestingly, it is the only language that operates natively with the web browser, although it can also be used from the server.

Back-end programming tools and languages


Java is the most widely used back-end language today and its uses go way beyond just app and web development. Most large corporations, (if not all!) use Java in the backend, which is why the demand for Java programmers is so high. Java was first made commercial as a programming language and computing platform in 1995 by Sun Microsystems and it has always been fast, secure, and reliable. From laptops to data centers, game consoles to supercomputers, and cell phones to the Internet, Java is everywhere.


A popular alternative to building applications with Java is to use JavaScript together with a set of tools known as MERN. MERN consists of four open-source components: MongoDB, Express, React, and Node.js. With this set of tools you can build the frontend and backend of an application only using JavaScript.

When creating a website or mobile app, you have to find somewhere to store all the data that powers your service. Part of a full-stack developer’s job is to handle the databases that store such data and know how to operate them.

Web architecture

Full-stack developers are also responsible for structuring apps so they are efficient, effective, and easy to maintain. All these elements are solved through the architecture design. Good architecture contains three layers: presentation, business logic, and data that reside on two computers, presentation and logic (frontend) on one side and logic and data (backend) on the other.


Finally, in modern software development projects where dozens of programmers work either asynchronously or at the same time, developers use version control software to help productivity, security, organization, and project management. Git (and GitHub) is the most-used tool by professionals. Creating a profile on GitHub is absolutely essential for coding team work and highly recommended for individual work too.
