Summary

Currently a Technical Fellow at Walmart Global Tech working on identity (IAM) platforms and AI agent infrastructure. Before that, I led infrastructure efforts for Streamlit Cloud, various platform features for Snowflake Notebooks, and built observability platforms at AWS (Prometheus and Grafana managed services). At Amazon Ads I was a principal engineer responsible for engineering excellence across a large engineering organization to improve reliability, scalability, and development velocity across dozens of teams and systems.

I have spent most of my career building distributed systems at Amazon, Google, Snowflake, and now Walmart, with over 30 years developing software from from ad serving platforms to observability services to AI/ML systems.

My recent work has focused on building platforms and services that help other engineers ship faster and operate more reliably—whether that’s CI/CD infrastructure, observability tooling, or runtime platforms. I enjoy the technical challenges of distributed systems and the organizational challenges of helping teams ship better software faster and more reliably.
