What I'm looking for

I'm looking to lead architecture and delivery for high-throughput, real-time, cloud-native platforms, while mentoring engineers and improving production reliability through practical automation and scalable system design.

I've built and modernized high-throughput, low-latency platforms across Caesars Sportsbook, iHerb, XTIVIA, and TK20. My work spans sports betting, e-commerce, government, healthcare, and insurance.

At Caesars Sportsbook, I architected a Java, Spring Boot, and Kafka ingestion platform that supported weekly hold growth from approximately $300K to $5M. I also designed Go, gRPC, and Linkerd services processing millions of messages per second, and led a five-engineer platform team through architecture decisions and production incidents.

At iHerb, I created a JSON-driven rules engine processing approximately 10 million customer messages daily and helped contribute to a $25M revenue lift within six months. I reduced campaign implementation from weeks to hours and improved release cycles by 40% through feature flags and Kubernetes-based continuous delivery.

I've led teams, client engagements, design reviews, and cloud-native modernization efforts using Java, Go, C#, Kafka, Kubernetes, AWS, Azure, and AI-assisted automation. I enjoy translating complex business needs into reliable systems, reusable integration patterns, and practical delivery plans.
