Cloud Notes Application

A full-stack notes application built using Spring Boot, PostgreSQL, Docker, and Render. The application allows users to create an account, securely log in, and manage their personal notes through a simple web interface.

This project was developed to gain hands-on experience with backend development, RESTful API design, database integration, Docker containerization, and cloud deployment. It demonstrates the complete software development lifecycle, from designing the application architecture to deploying it as a live web application.
