Hello! 👋

I'm Zaher

Healthcare Analytics & Data Engineering

About Me

I build healthcare analytics as products, not reports. My work spans population health, data engineering, and clinical operations, focused on scalable systems that connect revenue, cost, and quality in real-world complexity. I welcome conversations around population health and analytics designed to integrate cleanly into complex software systems.
