# Payment-Processing-Service

This project involves developing a core payment system for an e-commerce client using Stripe and Razorpay payment gateway integration.

The project is built using Java and Spring Boot, utilizing microservices architecture. It focuses on providing a reliable, scalable, and secure payment processing system.

Developed a robust payment processing system using Spring Boot for backend development.  

Integrated third-party payment APIs (such as Stripe, Razorpay.) for processing transactions. 

Built RESTful APIs for efficient handling of payment requests and responses.

## Key Features

- **Stripe API Integration**: Seamlessly integrated Stripe for handling payments, including processing notifications and managing payment statuses.

- **Microservices Architecture**: Utilized a modular approach to develop independent services such as payment processing and Stripe provider services.

- **High Performance**: Implemented thread pools and optimized error handling mechanisms to ensure high performance and reliability.

- **Security**: Integrated security layers and used Stripe-provided authentication mechanisms to protect sensitive payment data.

- **Asynchronous Processing**: Leveraged ActiveMQ for asynchronous communication within the e-commerce system.

- **Robust Error Handling**: Developed an error handling system with custom error codes and utilized Spring exception handling for effective error management.

## Responsibilities

- Designed and developed Stripe integration using Java, Spring Boot, and microservices architecture.

- Analyzed Stripe integration documentation and collaborated with the team to finalize the integration approach.

- Built a payment status tracking system to ensure 100% payment reliability.

- Contributed significantly to the design and development of the core payment processing logic.

- Implemented Stripe-provided authentication mechanisms while integrating third-party Stripe REST APIs.

- Coded and unit-tested the Stripe notification handling layer.

- Developed a modular payment processing service.

- Created multiple error codes to handle system failures, utilizing Spring's exception handling capabilities.

- Applied design patterns such as Factory and Builder patterns to develop a modular application.

- Worked with MySQL using Spring JDBC for database operations.

- Utilized AWS services such as EC2 and AWS Secrets Manager for deployment and security.

- Independently explored and integrated ActiveMQ for asynchronous communication.

- Awarded STAR Performer of the Month for delivering tasks on time and supporting the team in meeting sprint deadlines.

- **Frameworks**: Spring Boot, Spring Boot JDBC

- **Architecture**: Microservices

- **APIs**: RESTful APIs (JSON), CURL, Postman

- **Database**: MySQL (RDS)

- **Version Control**: Git, BitBucket, SourceTree

- **Build Tools**: Maven

- **Application Server**: Tomcat

- **Testing**: JUnit, Mockito (Unit Testing, Mocking, Code Coverage)

- **Cloud Platforms**: AWS (EC2)

- **IDEs**: Eclipse, DBeaver

- **Asynchronous Technology**: ActiveMQ

- **Methodologies**: Agile, Scrum

- **Project Management**: Jira

- **Logging & Debugging**: Log4J/Logback, Eclipse

- **Tools**: GSON, Lombok, SonarLint, MobaXterm

## Key Learnings

- Gained in-depth knowledge of integrating Stripe payment gateway using Java Spring Boot.

- Enhanced skills in building microservices-based architectures for scalable applications.

- Acquired hands-on experience with AWS cloud services and security management.

- Improved understanding of asynchronous processing and real-time communication using ActiveMQ.

- Strengthened debugging, troubleshooting, and problem-solving skills.
