What I'm looking for

I am seeking senior backend or architect roles in fintech where I can design scalable, secure payment systems, lead teams, and drive cloud-native, test-driven delivery with strong CI/CD and compliance focus.

I am a seasoned software engineer and architect with over 17 years of experience designing, developing, and supporting robust business applications, primarily in fintech and payments. I have a strong foundation in object-oriented design and have led end-to-end delivery of cloud-native microservices, payment processing engines, and secure third-party integrations while emphasizing TDD, high code coverage, and scalable CI/CD pipelines.

My work includes architecting critical payment modules (ACH, Wire, RTP), ISO20022/SWIFT integrations, OFAC screening, and modernizing monoliths into microservices on AWS and Azure using Docker and Kubernetes. I have led teams, collaborated across product/DevOps/QA, and delivered resilient, high-performance systems integrating Kafka, Spring Boot, and enterprise security and compliance tools.
