What I'm looking for

I'm looking to lead architecture and hands-on delivery of cloud-native, event-driven Java platforms, contributing to design decisions, scalable APIs, CI/CD, observability, and AI-focused proof of concepts.

I've built cloud-native microservices and event-tracking platforms for Best Buy, including Trace Flow and Customer Value Calculator solutions using Java, Spring Boot WebFlux, Kafka, IBM MQ, RabbitMQ, GCP, and AWS. I also developed Semantic Asset Registry and Feature Store solutions with GCP Pub/Sub, BigQuery, Dataflow, GCS, Firestore, and observability tooling.

Across the Connecticut Department of Social Services, Nokia, Mindtree, Tata Consultancy Services, and Totality Software Technologies, I've led architecture and delivery for mobile APIs, telecom workflows, insurance applications, and product costing systems. I bring 19+ years of experience taking requirements through architecture, implementation, CI/CD, testing, deployment, and production support.
