What I'm looking for

I’m looking for a Java microservices role where I can improve reliability and performance in regulated environments, own API and observability practices, and deliver measurable outcomes with clean architecture, testing, and continuous improvement.

I’m a Senior Software Engineer with 17 years of experience building and operating production systems across fintech, healthcare/benefits, insurance, defense, aviation, and telecom. I’m known for delivering measurable outcomes in complex, regulated environments with a strong emphasis on reliability, maintainability, and performance at scale.

My core expertise is Java and Spring Boot microservices—designing REST APIs, implementing Hibernate/JPA data access, and building robust asynchronous workflows. I bring hands-on experience across Python, Docker, Kubernetes, RabbitMQ, and observability with DataDog (APM, distributed tracing, logging), so systems stay diagnosable under real-world load.

Across roles, I’ve improved production results by tightening data and workflow correctness, optimizing performance, and raising engineering quality through testing. For example, I built an internal validation service that pre-validated IRS transmission files to significantly reduce downstream rejection risk and “accepted with errors” responses.

I also enjoy continuous delivery work—incremental enhancements to queue processors and schema-change pipelines, instrumenting API tracing end to end, and using Agile/Scrum with CI/CD principles. From leading a 5-person integration effort on Delta’s W-IFE system to modernizing insurance and pharmacy platforms, I stay practical: ship confidently, measure impact, and keep systems resilient.
