Who am I?

I graduated from the University of Texas at Austin with a BBA in Management Information Systems (McCombs School of Business) and a minor in Computer Science.

Throughout my career spanning Chevron, Glassdoor, and now Google, I have specialized in bridging the gap between business operations and highly technical data architectures in order to drive revenue growth. I enjoy designing clean, scalable ETL pipelines, optimizing data footprints, and deploying custom software tools that make engineering operations seamless.

Beyond core data engineering, I have a passion for building AI-driven applications, interactive maps, and analytics dashboards.
