Trending: How To Hire A Back-end Developer In 2020

Introduction

Try booking yourself a set of movie tickets or shopping from an e-commerce app. Even simpler, enter something on the browser. Are you wondering how the content is continually changing and updating with real-time data or amazed at how you’re getting suggestions without typing all the details? It seems like magic doesn’t it? All this is a part of a detailed behind-the-scenes process commonly known as ‘Back-end Development.’ The back-end is all about maintaining a strong online presence while keeping the audience engaged with a unique set of technologies and languages. It powers the product’s growth, making the entire process of online browsing seamless.

What Is Back-End Development and the Role of a Back-End Developer?

Back-end web development is the backbone of software development. It is the process of writing codes that communicates with the front-end and shares relevant information to be displayed on the screen. The interaction happens through a series of requests sent to the back-end servers that store millions of terabytes of data, to help dynamic software maintain their elective presence and keep users interactively engaged. Back-end development also ensures that the software doesn’t crash often or have 404 errors that restrict the overall performance of the page. Now, all this is not powered by AI yet; it is done manually. It is thereby creating a high demand for proficient and experienced back-end developers. 

What Is The Role Of A Back-End Developer? 

A back-end developer is responsible for creating, maintaining, testing, and debugging the entire back-end. This requires a massive investment of time, patience and knowledge to master the art of just one language. One language alone is so exhaustingly comprehensive that the back-end engineer must be deeply involved in knowing its entire architecture. Additionally, back-end languages continually modify with upgrades and updates. In such a scenario, back-end developers can’t or rather shouldn’t afford to move to new languages and be a jack of all trades. This would reflect on their knowledge and skills.

How To Hire The Best Back-end Developer For Your Organization

The back-end is a critical component of both your website and the company’s success. Hence, in a digitally evolving world, your decisions can no longer be based on resumes and instincts. Your approach to finding an ideal back-end candidate is backed by a clear understanding of the skills and expertise relevant to both the tech stack and your business.

To help you take a closer look at the necessary skills set that summarizes the role of an ideal back-end software engineer, we’ve divided your hiring process into two parts.
