Back-End development Explained

Before defining back-end development by answering what back-end programming is, let’s zoom out on our conversation to find out how we got here. All websites, software, and apps have client and server sides. Front-end developers write the code (logic) that powers the client side. In contrast, back-end developers like offshore ruby on rails developers write the code that powers the server side of any software, app, or website. And you can find and hire professionals working remotely in Ukraine. 

In addition to writing the code needed to create a database, back-end developers also write the code that builds out the server and application sides. These professionals also handle API migration, Server performance enhancement, and database migration. 

What skills do you need to be a back-end developer?

Now that you have a picture of a back-end developer and what back-end development entails, let us discuss some of the skills you will need to excel as a back-end developer.

Python aside, it will also be best to get acquainted with Java– which many people confuse with JavaScript. 

Back-end developers need to familiarize themselves with Java — a general-purpose programming language that facilitates app development. Java allows the creation of robust systems, and developers use IDEs (integrated development environments) when compiling code using the programming language. 

Code written in Java can then be compiled into low-level code which software interpreters can understand. 


Commonly known as a hypertext preprocessor, PHP is one of the preferred programming languages among back-end developers. PHP allows programmers to script, which explains why it is referred to as a scripting language.

Simply put, scripting is the interpretation of code or scripts, and it helps developers automate and enhance routine processes in their code.
