Do you know what Front-end and Back-end are?

As technology advances, these development areas are becoming increasingly important and are constantly sought after by professionals who want to specialize—and even become Full-Stack developers.

Because they have different characteristics and more specific languages, having strong Front-end and Back-end work is fundamental for your app or web system to be high quality and gain a competitive advantage.

What is Front-end?

A front-end developer is responsible for building application interfaces that interact directly with users and, working together with design, helps deliver the best possible user experience.

Front-end is the first layer we come across in a software product, with the purpose of presenting visual information.

The information provided by the front end is present in every platform we use—from a news portal with large video and text reports to e-commerce sites with contact registration forms and search buttons—created based on data and rules that live in the back end.

From upload to download, front-end programming enables many activities to be done online, personalizing the user experience according to the business.

There are several languages and technologies focused on visual formats. The most common are HTML, CSS, and JavaScript, each with different functions but the same goal when we talk about front-end.

What is Back-end?

A back-end professional is responsible for building the internal layer of a system: everything involving databases, executing site features, and processing data obtained from the front end.

Behind the scenes sits the back-end code, and end users do not have access to it because it runs on the server where the application is hosted. When a user accesses the system and requests some “information”, the language used by the developer interprets the message and sends a response to the browser.

In this area, rigor and care with data are crucial. After all, the code makes up the system and drives performance—and keeping the process secure is a sensitive, high-value requirement.

Some of the main programming languages used are Java, C#, PHP, Python, and Ruby. All of them are widely used for back-end development for web systems and apps.

What is a Full-Stack developer?

A Full-Stack developer is a well-rounded professional who can work comfortably in both areas. In other words, they can build an entire system without needing help from a front-end or back-end specialist.

Most of the time, Full-Stack developers are more experienced professionals who have spent a long time working with both front-end and back-end.

Because of that, for those starting a development career, an important tip is to focus on one area first—especially if you’re interested in becoming Full-Stack later.

Given the large number of technologies that exist today, trying to learn both areas at once can hurt your progress and you might end up not specializing in either.

Conclusion

In summary, Front-end developers are responsible for the entire visual part of a system and for the layer that interacts with the final customer/user, enabling interactivity.

Back-end specialists, on the other hand, build the structural part of an app or web system: database development, system reliability, and even digital security.

Bringing both areas together, there are professionals who specialize in both, known as Full-Stack developers. In many cases, they are more expensive to hire because of their experience across a wide range of programming languages.

So—do you already know what type of developer is best for your business?

To make it even easier, you can build your squad based on specific programming languages and the professional profile you want.
