Front-End Developer
In recent years, the role of a Front-end Developer has become more complex as they must consider and combine many diverse factors: features, structure and aesthetics of the interface. This not only required them to create an optimal interface, but also ensure consistent display across a variety of devices, including smartphones, tablets, and personal computers.
Front-End Developers often work with multiple programming languages, such as HTML, CSS, and JavaScript, to define the structure and operation of applications and software.
Back-End Developer
If the Front-end Developer is the one who builds the “outside” of a house, the Back-end Developer is responsible for the basic system, electrical wiring and internal connections. They are the people who build the way an application or software works.
Back-end Developer’s work often focuses on two main aspects: server and database. While the database contains all the information (like user profiles and product lists), the server is responsible for handling requests from users.
Back-end Developer interacts directly with data, application integration, APIs, and other back-end processes. This role requires extensive technical knowledge and the use of many different back-end programming languages.
Full Stack Developer
As the name Fullstack suggests, they are capable of doing both Front-end Developer and Back-end Developer work. They can flexibly switch roles based on needs, and especially have the ability to perform both roles when necessary.
When taking on both aspects of their work, they must ensure strong integration between front-end and back-end elements in one operational system. When users interact with a feature on the application interface, that interface automatically responds to any requests they make.
Mobile Developer
Mobile Developers are experts in creating software and applications specifically for mobile devices. Developers in this field must build applications that are compatible with two important platforms, Android and iOS, each with its own unique characteristics.
According to data from Statista, in 2021 alone, there were 230 billion downloads of applications to mobile devices. This number demonstrates the popularity and necessity of the Mobile Developer position in the technology market, as well as the constantly increasing demand of businesses wanting to have their own applications.
To become a Mobile Developer, you need to be proficient in some popular programming languages for mobile devices, such as Swift, C#, and Java.
