How to Hire a Full Stack Developer Fast

Today, when hiring software developers businesses have to consider their competencies and the tech stacks they work with. Though, just about 20 years ago there wasn’t so much clear division of specializations. One software developer could work with an application’s front-end, back-end, databases, testing, and more, creating the solution from start to finish. Basically, at that time every developer was a full-stack developer.

Does this mean that nowadays companies don’t need full-stack developers anymore? In reality, the demand for full-stack developers is only growing. According to LinkedIn’s 2020 Emerging Jobs Report, full-stack developers are considered “a valuable asset to any company” with a hiring growth rate of 35% since 2015. So, why do companies hire full-stack developers, and how to find and hire a good one for a software development project? Let’s find it out. In this article, we explain when to hire full-stack developers and share the questions that can help find qualified full-stack specialists.

Who Is a Full Stack Developer?

A full-stack developer is a specialist who sees the full picture of the developed application. It means that they know how to work with the three layers required to build a successful solution – the presentation layer, logic layer, and data layer.

Who Is a Full Stack Developer?

Each layer has its own set of tools, programming languages, and frameworks which are piled in “stacks”. Therefore, a full-stack developer is a specialist who knows how to use tools, languages, and frameworks from the three application layers and can create an entire application themselves.
