Our world is dependent on technology, and we rely on devices and the internet to help us through daily tasks. But, how does that technology allow us to thrive, and who’s putting in the work to make it happen? Usually, a backend developer skilled in coding languages and frameworks connects users to apps, platforms, and systems on the web.

If you’re not too familiar with the terms frontend or backend development, it can be difficult to wrap your head around what that means. In this guide, we’re going to break down what backend development is and how it benefits you, alongside why it’s important to hire a backend developer for your company.

What Is Backend Development?

A tech stack is a group of different technologies such as programming languages, frameworks, and tools used to build web and mobile applications. The two main factors of any web application are front-end (client-side) and back-end (server-side).  

 

Front-end is what the user interacts with, which could be browsing a website or using a social media app like Instagram. Backend development goes on “behind the scenes” for the web app to function correctly; it’s the coding that happens server-side and connects the internet to servers, databases, users, and applications.

 

The backend development actually runs the entire application and allows it to function as it was intended to. The front-end development works in conjunction with the back-end to produce a final product for the end-user.

What Does a Backend Developer Need to Know

There are many responsibilities and skills involved in completing a backend developer’s job. Firstly, you’ll need to be skilled in developer languages and frameworks.

 

A backend developer’s responsibilities will include creating libraries, writing database code, writing API’s and working on data architecture. Depending on which company the engineer works for or the client’s needs, a developer may be required to work with a specific language or even multiple to achieve the desired outcome.

 

The programing languages a backend developer uses are either object-oriented (OOP) or function. Object-oriented programming consists of creating objects, and some of the most popular OOP languages are Java, Python, and C++. Functional programming is a technique that’s more action-based, it’s usually used for data science, and some of the most popular languages are SQL, F#, and Clojure.

Then there are also versatile programming languages like Javascript, which are now considered both OOP and functional because of their features.
