🛒 ShopEase – Microservices-Based E-Commerce Platform

Overview

ShopEase is a scalable, modular e-commerce platform built using a microservices architecture. It demonstrates modern software engineering practices including MVC design, RESTful APIs, relational database modeling, and third-party payment integration with Stripe & Razorpay. Core services include User Authentication, Product Catalog, Payment Service, and Service Discovery.

🔧 Key Features

• User Management: Registration, login, and role-based access control.
• Product Catalog: Category-wise inventory management with product image support.
• Order & Payment Processing: Secure order placement via Stripe & Razorpay checkout sessions with success/failure handling.
• Service-Oriented Architecture: Independently deployable microservices with service discovery for dynamic routing.
• Database Design: MySQL-based normalized schema using foreign keys and indexing for performance.
• Error Handling: Custom exceptions (ResourceNotFoundException, etc.) for user-friendly error reporting.

💻 Tech Stack

• Backend: Java, Spring Boot, Spring Web, Spring Data, Spring Cloud
• Database: MySQL, Hibernate ORM
• Payment Gateway: Stripe, RazorPay
• Caching: Redis
• Tools: Lombok, JPA, Maven, JUnit, Mockito
• Service Discovery: Netflix Eureka

🚀 Project Highlights

• Stripe & Razorpay Integration: Secure and production-grade payment handling.
• Performance Optimizations: Indexed queries and planned Redis caching to reduce latency.
• Scalable Design: Microservices allow independent scaling and easier maintenance.
• Queuing Service: Asynchronous messaging with Kafka for order and email processing.
• Extensibility: Well-suited for frontend integration (e.g., React, Angular).
• Automation & CI/CD Ready: Maven-based project structure, suitable for Jenkins or GitHub Actions.

⚠️ Known Limitations

• Stripe / Razorpay transaction costs may affect small-scale apps.
• Caching needs proper invalidation strategies.
• Monitoring and observability tools like ELK Stack or Sentry are not yet integrated.

🔄 Future Enhancements

• Frontend implementation using React or Angular.
• Implementation of Spring AI.
• Integration of APM tools like New Relic for observability.
