A fullstack developer is a programmer who is skilled in both front-end and back-end development. Front-end development involves creating the visible parts of a website or application that users interact with, such as the user interface and design. Back-end development involves working with databases, servers, and the logic that powers the front-end. A fullstack developer is capable of working on all aspects of a web application or software product, from the user interface to the server-side logic.

Back-end Development: Fullstack developers are proficient in server-side programming languages like Python, Ruby, Java, or Node.js. They can build the back-end infrastructure, handle data storage and retrieval, and create APIs (Application Programming Interfaces) for communication between the front-end and back-end components.
