Executive Summary
Data engineer in healthcare analytics, building the pipelines that put claims and clinical data in front of quality teams before the morning huddle. Eight years moving from reporting into engineering, now owning ingestion, transformation and testing in Snowflake and dbt for a population health platform used by 30 provider groups.
Signature Achievements

- Cut Snowflake spend by 31 percent by replacing full reloads with incremental models and resizing two warehouses.
- Added 240 data quality tests in dbt, catching a bad member file before it reached a report rather than after.
- Reduced the time to onboard a new provider group from six weeks to nine days with a templated ingestion pattern.
- Retired 90 legacy stored procedures and moved the logic into version controlled models the analysts can read.
