The term “developer”, however, has now become very generic as under this heading there are actually very different tasks and functions. In fact, developers usually specialize in certain programming languages and activities which aim to create and manage different aspects of a web site.
In particular, three types of developers can be identified: Front-end developer, Back-end developer and Full-stack developer. What differentiates these three figures? Let’s try to find out more:
Front-end developer: skills and tasks
Back-end developer: what it does
The Back-end developer, on the other hand, works “behind the scenes” of a website. In fact, when you Hire back end developer, it takes care of its server-side operation and of interventions that have no impact on the graphical interface and therefore on what users see by visiting the site. At the coding level, the Back-end developer usually uses languages like PHP, Python and Ruby.
Full-stack developer: what it deals with
Understanding a full-stack developer
In this sense there are many languages and frameworks that a full stack developer could know and use, but it is not essential that he knows them all. It would be sufficient to focus on some of the main technologies and gradually, thanks to the experience in the field, which keeps updating and learning new ones based on the needs and demands of the market.
According to the results of the Stack Overflow Developer Survey 2017, 63.7% of web developers define themselves as full stack. This clearly does not imply that everyone knows all the backend and frontend development technologies available, but that they are able to operate effectively on both fronts because they have experience of the logic that regulates them.
Essential technologies for a full stack developer
As far as backend technologies are concerned, it is not easy to define which one is best to learn: even in this case the understanding of the logic of development and creation of databases is becoming increasingly important as well as the in-depth study of the chosen language. Among the most widespread backend technologies to choose from there are certainly SQL, Java, Python and PHP. NodeJS is another valid additional option. Being a JS development environment does not require the knowledge of a new language.
Last but not least is the knowledge of databases to store data: relational like SQL (which remains the most widespread), non-relational like MongoDB and the connections between them and the chosen backend language.
There are those who enjoyed comparing the back-end and front-end developer to two professionals who work side by side to set up a house: the back-end developer takes care of creating the foundations, the walls, the network of pipes and everything related to infrastructure, while the front end developer has the task of making the house livable by taking care of access to services (switches, taps) and the stylistic and design side. As you can easily guess, the full-stack developer will, instead, be an all-rounded figure that can handle every aspect of an application development. Becoming a good full-stack developer obviously requires time and experience. For this reason the most common working situation is that of a team, where back-end and front-end developers work side by side, comparing each other to build the best possible user experience.
