About Full-Stack Developer - The Versatile Developer

Most developers spend the majority of their careers professionalizing themselves in a certain area. As for Full-Stack Developer, they are knowledgeable from server, data, front-end to back-end, UI, UX, ... So whether they are technology geniuses in the whole team or not.

The Definition of Full-Stack Developer

Full-Stack is a combination of knowledge, visual and deep understanding of both front-end and back-end, as well as having a thorough understanding of best practices and concepts. Front-End is generally the component for the user to see and interact with, the Back-End is the part of the application with processing logic, database interaction, user authentication, server configuration.

Obviously, Full-Stack Developer is the person having the capability to work in both the front-end and the back-end of the product, concurrently code for all components of the system. It requires a large number of skills as well as experience.

In general, Full-Stack Developer is usually responsible for designing the interface and the database behind it until the product runs smoothly.

Although assuming responsibilities for both the front-end and the back-end of an application, a full stack developer will not be as good as a front-end expert in processing the front-end, this is similar to the back-end. However, they will have a broad understanding of many different components, how to interact between them in the development process and combine them into a complete product.

As a Full-Stack Web Developer, you don't necessarily have to do all the tasks that are delivered from the front-end to the back-end, but that means you can work on both front-end and back-end, understand what is happening when building an application.
