Ndlovu Drone Shop - Spring Boot Application

JAVA FRAMEWORKS

Project Scope

A fictional company has been created for a customer who is passionate about flying drones for activities such as aerial photography and exploring locations inaccessible to humans. Their enthusiasm led them to start a business that not only sells drones and accessories but also offers blogs to help fellow drone enthusiasts select the right equipment for any task or adventure.

My collaboration on this project was instrumental in making the website fully functional by implementing CRUD (Create, Read, Update, Delete) functionality and ensuring logic was in place to validate entries and operations. Below is a detailed walk-through of my contributions, outlining the changes made and where they can be found within the project.
