About me

I'm a software / data engineer who builds the pipelines and infrastructure that make ML and analytics possible. My career has spanned healthcare data, big-tech AI infrastructure, and medical device data systems.

These days I'm at IntusCare, building ETL for complex PHI datasets with dbt, Airflow, and Airbyte. Before that I spent a year and a half at Apple on AI/ML data ops — leading a multi-format booking-data pipeline and designing automated PII detection across 12+ locales.

Off the clock I'm usually surfing, rock climbing, or hanging out with my dog Ghost. Lately I've been teaching myself game development in Godot.
