• Architected end-to-end Payment Processing for 5+ Payment types and implemented critical components of Payment Lifecycle like Decryption, Parsing, Persisting, Filtering, Error Handling, Validation, De-duplication, and Computation. Built a scalable architecture capable of concurrently handling Payment Posting for approximately 500 payments.(Java 8, Spring Framework, Microservices Architecture, Kafka, Agile)• Developed process to consume these Posted Payments using various Microservices for Parsing, Account Derivation, Balance Check, Sanction and Account Posting (API Development)• Implemented System Integration Testing using Cucumber for different payment types and flows in SEPA, and elevated Unit Testing Code-coverage from 45% to 80% • Collaborated with over 7 teams, integrating their APIs and RESTful Web Services into the Payment Processing system. Transformed data seamlessly into varied formats like JSON, XML.• Enhanced Jenkins configuration, optimizing the rerun of test suites from failure points, resulting in heightened developer productivity and resource utilization. Managed 100+ scenarios efficiently.(Jenkins, Continuous Integration (CI), Continuous Deployment (CD))• Acknowledged with recognition and award from colleagues and managers for steering the Payment processing initiatives within the SEPA team
