About

I'm a Data Analyst at the New York State Department of Health, where I work with large-scale health data to deliver insights that support high-level decision-making. My core responsibilities include:

  • Writing complex SQL queries across Oracle, Vertica, and enterprise data warehouses
  • Designing interactive Tableau dashboards to visualize key health metrics and trends
  • Creating detailed design documents with SQL logic, data definitions, business rules, design steps, requirements, context, and key questions for cross-divisional use
  • Collaborating closely with project managers, business analysts, research scientists, and fellow data analysts to align technical solutions with organizational goals
  • Simplifying complex datasets to drive actionable insights for public health initiatives

With over a decade of experience across education, logistics, retail, EDI, and petition data, I bring a diverse analytical background and strong technical foundation. I've taught computer science and software engineering at the university level, built predictive models to improve supply chain operations, and ensured data accuracy in civic tech systems. Across roles, I focus on clarity, efficiency, and transforming raw data into meaningful results.
