About

I'm a senior data engineer with 14+ years of experience building data platforms at scale. Currently at Sam's Club (Walmart), where I've architected privacy-first media data platforms, identity resolution systems handling 200M+ identities, and a petabyte-scale BigQuery warehouse serving as the foundation for self-serve analytics across a $93B business.

I hold U.S. Patent 12141166B2 for a manifest-based incremental synchronization framework across Azure Delta Lake and GCP BigQuery — cutting sync costs by 90%.

I write about data engineering and AI agent systems. Three of my engineering posts were featured in Walmart CTO's weekly communication, covering agent communication patterns, RAG evaluation strategies, and turning git history into engineering insights.

Before Walmart: NLP research and machine translation systems, computer vision research at the University of South Florida (M.S. Computer Science, 3.96 GPA), and earlier engineering roles at Capgemini, Wipro, and Dell.
