What I'm looking for

I'm looking to lead architecture and product development for scalable, compliant FinTech platforms, combining cloud-native payments modernization, AI-first design, engineering leadership, and cross-functional partnership.

At Barclays, I build and scale enterprise FinTech solutions, modernizing traditional bank transaction systems for payments and collections.

I design event-driven, microservice-based architectures using messaging, domain-driven models, reusable APIs, and cloud-native patterns on AWS and OpenShift. My work spans ISO 20022 PAIN/PACS messages, SWIFT MT, NACHA, and real-time integrations.

Previously at Citi, J.P. Morgan, Horizon Blue Cross Blue Shield of New Jersey, and Broadridge, I delivered backend services, workflow automation, claims applications, and ProxyEdge ballot-processing components. At J.P. Morgan, I improved Client Onboarding workflows through Spring MVC services, Oracle stored procedures, query tuning, caching, and jQuery/AJAX enhancements.

I lead through code and design reviews, mentor engineers, and partner with Product, Operations, Risk, and Compliance to deliver scalable, compliant, high-availability systems. I also apply AI-first solution design with GenAI integrations on Claude, Co-Pilot, and MCP lifecycle management.
