1. A full stack service with 3 years of experience would likely be a robust and well-designed web application that is built to handle a variety of different user needs.
It would be built with a variety of front-end and back-end technologies (interface graphic, scripting ... )
including languages such as :
- JavaScript - Nodejs, JQuery, React
- PHP - Laravel
- Java - Spring boot
- Python - Flask , Django
The service would be able to handle a large number of concurrent users, and would be optimized for performance, scalability, and security.
