What I'm looking for

I’m looking to lead end-to-end product engineering—owning APIs, React experiences, and secure cloud deployments—while applying AI-assisted automation responsibly to improve operational workflows in regulated industries.

I’m a Senior Full Stack Engineer with 14+ years building scalable enterprise applications across healthcare, banking, retail, and gaming. I specialize in Java, Spring Boot, React.js, TypeScript, cloud-native APIs, microservices, and production-ready web platforms, with a strong focus on secure integrations, observability, and system modernization.

In healthcare, I’ve delivered AI-assisted clinical workflow automation that improved triage speed, reduced authorization follow-ups and lookup delays, and increased care-team productivity through better workflows, dashboards, and secure messaging. In regulated finance and high-traffic retail systems, I’ve strengthened reliability through API design, test coverage, and CI/CD-backed deployments on AWS/Kubernetes, while enhancing auditability and access control with OAuth2/JWT/RBAC and improving performance with high-performance search and robust data pipelines.
