With everything going digital, the demand for full-stack developers has gained new heights. Every company wants their product to go digital, so they need to hire full-stack developers who can create a website for the company from scratch.
Full Stack Developers are in high demand owing to their diverse coding skills. Smart organizations prefer to hire one full-stack developer, rather than hiring two or three engineers to do the same job.
But, hiring a full-stack developer is like finding a needle in a haystack. It's a tough challenge for a recruiter because not every other developer is good at both front-end and back-end development. That’s why recruiters show utmost care while recruiting a full-stack developer.
1. Who is a Full-Stack Developer?
In layman’s terms, a full stack developer is good at every domain like front-end development UI/UX, backend development, DevOps, cloud computing, etc. Most importantly, he/she can adopt new and trending technologies fast.
Full Stack developers can develop any complex application from scratch, with the proper understanding of how each technical layer (mainly Presentation, Business logic, and Database Layer) should integrate with the other.
In most firms, a full-stack developer gets his team switched every 6 months. This means he/she has to follow the trend i.e. he should be a “jack of all trades, master of none”.
