What I'm looking for

I'm looking to lead architecture and delivery of scalable, high-throughput Java middleware and API platforms, partnering with stakeholders on solution design, performance optimization, cloud integration, and team guidance.

I've designed and optimized Java-based middleware and APIs for EY GDS, JP Morgan, NTT DATA, and Mphasis across 15 years of enterprise delivery.

At EY GDS, I lead architecture for a distributed, message-driven workflow service built with Core Java, Spring Boot, Apache CXF and MariaDB I also designed Salesforce-to-MariaDB replication using microservices and Kafka.

I've improved reliability under peak demand through JVM tuning, connection-pool optimization, microservice scaling, and concurrency controls. My work includes email delivery and shift-validation systems, financial integrations, GDPR compliance, billing orchestration, and tax-compliance APIs.

Earlier, I delivered secure RESTful services for JP Morgan's DASH Service and contributed to enterprise web applications at NTT DATA and Mphasis. I take projects from requirements and solution design through implementation, reviews, deployment, and production support.
