What does a software developer do?

The tasks of a software developer are to plan, implement, test, and introduce IT systems. In reality, the actual objectives may vary in different companies.

If a company has a system analyst, the functional or logical part of planning will not be part of a software developer's work, given that understanding business processes and making a functional specification and logical system plan based on them is the system analyst’s job. In this case, the software developer s still undertakes some planning tasks but only the ones that are related to realization. (Naturally, understanding the processes is still essential)

Similarly, if there is a tester in the project team, the software developer may focus their testing tasks mainly on unit testing. Moreover, the software developer limits their testing tasks as the role of a tester is to execute functional, integration and load testing.

If we would like to summarize the role of a software developer, we could say: the developer’s role is to implement the software according to the requirements, and to install it in a live environment or to deliver it for operation (in a tested and functional state).

Software developer roles

The list above was sorted based on job offers made for software developers.

There are many ways to sort software developers, but I think that the following list shows best what a software developer does.

Front-end developers

Front-End developers are software developers who write the code that runs on the user interface, in other words in the browser. Nowadays it usually means: JavaScript developer.

Many people put an equal sign between front-end developers and JavaScript developers. Nowadays it might be true, but previously there were specific front-end solutions for both Java (Applet technology) and .NET (ASP.NET) platforms.

Back-end developers

They are developers on the server-side. In short, their objective is the development of multi-layer applications on the server, API development, and programming the execution of database processes. The work of front-end developers is directly visible because it appears on the user interface. Back-end developers, however, assure the invisible background for the software.

Full-stack developers

Front-end and back-end in one person. Note: Previously it was a completely normal phenomenon, however, after the separation of front-end and back-end, the value of experts moving around comfortably on the whole production line, those who are familiar with both parts, increased.

To sum up, a full-stack developer is required to know and understand the full technology stack.
