The process of building a web application from scratch, encompassing the front-end and back-end development, is known as full stack web development. Therefore, as a full stack developer, I am equipped with the knowledge and experience necessary to create a web application from the ground up, starting with the design of the user interface, adding server-side logic, and integrating it with a database to store and manage data. I basically Prefer MERN Stack and little bit JAVA and Android also. My responsibility as a full stack developer is to make sure the complete web application runs quickly and effectively for the users. I am able to work on the application's client and server sides and transition between various programming languages and technologies as necessary to provide an integrated and comprehensive online solution. Understanding the unique needs and requirements of the customer is the first step I take while developing a web application. From there, I build something that satisfies their needs and then work on the back end to add the required features and functionalities. This include developing APIs to connect with the front-end, writing code for server-side functionality, and integrating the application with a database to manage and store data.
