data engineer @ enGen — Highmark Health · Los Angeles, CA

I build and run ETL pipelines for healthcare claims and eligibility data — 20M+ records moving through Teradata and BigQuery in a HIPAA-regulated environment, with zero tolerance for silent data loss. Three years in, I care most about pipelines that fail loudly, validate themselves, and stay boring in production.

    • Consolidated 40+ raw source tables into a curated, analysis-ready layer serving 15+ analysts across 5 teams — the primary engineering contact for that data.
