What I'm looking for

I seek backend or platform roles where I can own services end-to-end, improve reliability at scale, mentor teams, and leverage GCP/Kubernetes to deliver measurable business impact.

I am a Senior Backend Software Engineer with 4+ years designing, scaling, and operating enterprise Java and Spring Boot microservices in high-volume production environments. I have owned 20+ services end-to-end— from architecture through deployment—processing thousands of financial transactions daily where accuracy and reliability were non-negotiable.

At Macy's I delivered measurable business impact by modernizing refund orchestration, improving customer satisfaction, and reducing lost units and processing time. I lead deployments, mentor junior engineers, maintain rigorous test coverage, and drive platform improvements across GCP, Kubernetes, MongoDB, and CI/CD tooling.
