Image Uploader built using Spring Boot, React and AWS S3. (React code not included)

This project was built to practice building a REST API in Spring Boot and connecting it to a front end.
I used an in-memory database with 2 users.
The web application allows users to drag and drop a photo which is sent to the backend which then updates the AWS S3 bucket.
Upon refreshing, the new profile picture is displayed on the web application.
