The best of back-end and front-end"},"content":{"rendered":"

In recent years we have seen a stratospheric growth in the number of professionals in the software sector. Similarly, the range of training courses related to new technologies and the development of technological training has exploded in response to the increased demand for these jobs by companies. This is not surprising, as software development and programming offer very competitive working conditions and reasonable career progression.<\/span><\/p>\n

Among the development jobs that have proliferated in the popular corporate imagery, three stand out in particular: front-end, back-end and full-stack developer.<\/strong> In this article we will tell you what the differences are between these three profiles and what exactly a full-stack developer does. Are they a \u201cunicorn\u201d job profile?<\/strong> Here we will discuss this controversial issue in the world of software development.<\/span><\/p>\n

Differences between front-end and back-end<\/strong><\/h2>\n

To put it simply, front-end developers are in charge of the more visual part of a website, program or application. Back-end developers, on the other hand, are responsible for the underlying architecture of the website, the storage of information in databases and maintaining an efficient connection to servers.<\/span><\/p>\n

Let's delve a little deeper into what it means to be a front-end or back-end focused developer:<\/span><\/p>\n

Front-end developer<\/strong><\/h3>\n

A front-end developer is responsible for creating the user interface<\/strong> (UI) of a web application. As we have said, it is in charge of the most visual part, that is, the part with which the user interacts directly. It uses mark-up languages such as HTML, CSS and programming languages<\/a> as JavaScript to develop the visual structure and ensure a good user experience. His main goal as an employee is to make the interface attractive, easy to use and functional on various devices and browsers.<\/span><\/p>\n

Back-end developer<\/strong><\/h3>\n

A back-end developer interacts with the databases<\/strong> to store and retrieve information at convenience, it establishes authentication methods<\/strong> of users, guarantees a secure connection<\/strong> in the requests between the interface and the server, among other tasks related to the more functional and logical aspects of the website or app. Depending on the project, back-end developers master different technologies, including Python, Java, PHP and Ruby.<\/span><\/p>\n

So what is a full-stack developer?<\/strong><\/h2>\n

A full-stack developer is nothing more than a developer who offers the complete package: is able to work on both front-end and back-end.<\/strong> That is to say, it handles several programming languages and can build an interface UX<\/a>-friendly and, at the same time, work with APIs and databases. So a full-stack works like a multi-purpose knife: it can create a new functionality on a website or app entirely autonomously, design a new web element with HTML and CSS and migrate data from one database to another.<\/span><\/p>\n

A full-stack developer could therefore be expected to is an all-in-one<\/strong>, This would be a developer with sufficient expertise and experience to be successful on both the front-end and back-end. But is this really the case? In this respect, many developers insist that the notion of a full stack is, if not a pipe dream, then nonsense.<\/span><\/p>\n

Some of the functions of a full-stack developer include:<\/span><\/p>\n
