Cloud Retail Billing Web Application

A real-world retail billing web application featuring AWS cloud media storage, product & category management, dynamic inventory, and Spring Boot REST APIs.

System Architecture & Overview

Project Narrative

I’m excited to share my second full-stack test project, a Billing Web Application developed for a real-world retail client. This project features category and product management, image upload and handling using AWS and local file systems, REST APIs built with Spring Boot, and a dynamic user interface developed with React and Bootstrap, including real-time updates along with search and delete functionality. Through this experience, I gained hands-on exposure to AWS, backend API development, and modern frontend practices, while also improving my self-learning skills and deepening my understanding of building scalable, real-world applications and integrating backend systems with cloud-based file handling. šŸ§‘ā€šŸ’»
