Pay is a Java-based payment service / microservices framework designed to support secure, scalable, and reliable payment processing workflows. It demonstrates core concepts in modern backend engineering such as REST API design, authentication, event-driven messaging, and cloud-native architecture — ideal for building payment platforms or financial microservices.

Pay is a modular payment processing backend implemented with Spring Boot, following best practices in API design, cloud deployment, and test automation. The project serves as a foundational skeleton for:

• Building secure payment APIs
• Integrating with third-party services or connectors
• Event-driven workflows
• Microservices communication patterns

💡 It can be extended with modules such as:

• Payment gateways (Stripe/PayPal/Adyen)
• Messaging (Kafka / RabbitMQ)
• Distributed transaction support
• Audit logs and reconciliation services

This project is ideal to showcase backend engineering skills in:

• Java (Spring Boot)
• Microservices
• Cloud infrastructure
• Messaging / event-driven patterns

• 🧠 Modular Architecture — Separation of layers for API, business logic, and data handling.
• 🚀 RESTful Endpoints — Designed for scalable payment operations.
• 🔐 Secure Authentication — JWT-based or similar secure login flows (configurable).
• 📦 Gradle Build System — Fast builds, dependency management, integration with tooling.
• 🧪 Automated Testing — Unit and integration tests for core modules.
• 📈 Cloud-Ready Deployments — Designed for deployment on AWS / GCP container platforms.
