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.
