EXPERIENCE
Data Engineer · Research Triangle Analytics · 2022-Present
• Rebuilt a Spark ingestion job with partitioning and pruning; cut nightly runtime from 5h to 70m.

• Built schema-change alerts; caught 3 upstream breaks before dashboards showed wrong numbers.
• Documented data contracts so producers knew what downstream consumers depended on.
• Key project — dbt testing starter: published model tests and freshness checks other analysts adopted.
