After many years of experience in web development area, people like to known as fullstack developer. Here is the very simple idea what is that?
Website development or application development has 2 parts:
- Frontend
- Backend
Now for frontend technologies there are many frameworks like React, Angular, Vue.js, jQuery etc
And for backend technologies there are many frameworks for different languages like for PHP it is Laravel, For Ruby it’s Ruby on Rails, for C# it is asp.net and for JS it is node.js etc.
Backend developer is not only expert of some framework but he/she must have to expert with server terminology & Database techniques.
So Backend = Application framework + Server knowledge + Database knowledge
When someone is expert of both frontend & Backend technologies called Fullstack developer.
