HOLLY HEBERT
Data Analyst
Summary
PhD-level data analyst who turns messy, multi-source data into decision-ready insight. 10+ years building KPI stacks, designing trustworthy experiments, and delivering executive-grade dashboards. Equal parts statistician and storyteller: rigorous with SQL/Python and causal methods, clear with stakeholders, fast with ambiguous asks. Comfortable owning the analytics layer end-to-end—from warehouse modeling and DBT transforms to BI rollout, documentation, and enablement.
