Project Description : Payment Hub is a middleware application that connects with partner services over various interfaces (MQ, Kafka, API, NDM, Tibco) to receive diverse payment types. Major functionalities include transforming payment messages using Java and Volante transformations and performing glueback processes in various ACH clearing flows.

Roles & Responsibilities :

• Developed and deployed modules for payment processing using Spring Boot and Microservices architecture.
• Created detailed technical design documents, including flow diagrams and API specifications, based on business requirements, facilitating efficient development and implementation.
• Conducted unit and integration testing using JUnit and Mockito, ensuring high code quality and reducing post-deployment defects.
• Provided technical demonstrations of developed modules to clients, effectively communicating system functionality and gathering feedback for iterative improvements.
• Troubleshooted and resolved critical production issues, including performance bottlenecks and data inconsistencies, minimizing system downtime.
• Identified and remediated security vulnerabilities, enhancing application security and compliance.
• Achieved cost-savings by developing functional solutions to problems.

Project Description: Project GCH is the heart of the payment system. It gets the payments in the form of XML from upstream application and converts or enriches the XML and sends the message in a format that downstream application accepts. It also sends the payment to other applications where the payments are checked for balance availability, address and other core information.

Roles & Responsibilities:

• Developed and implemented new features and services for a core payment system using Java and Spring Boot, adhering to customer requirements and business specifications.
• Conducted production support activities, including production replays, load testing, and exception analysis, to ensure system stability and performance.
• Migrated existing application flows to a PCF environment, leveraging cloud technologies to improve scalability and efficiency.
• Collaborated effectively with onsite teams, business analysts, and testers throughout the development lifecycle to ensure smooth project delivery.
