Know More About Me

As a Lead Software Engineer with 5+ years of experience, I build scalable backend systems and integrations in cloud-native environments at UPS. I specialize in Kubernetes, GitOps, and modern CI/CD with deep experience in Java-based middleware. I have a Master of Computer Science from University of Louisville and a Bachelor of Science in Computer Science from Indiana University. I focus on modernizing legacy systems, implementing declarative infrastructure, and accelerating developer velocity through automated pipelines. I architect secure, observable, and maintainable distributed systems across OpenShift, Azure, GCP, and AWS.
