Message

At Elevance Health, I develop AWS-based ingestion pipelines for healthcare data and process it through Bronze, Silver, and Gold layers in Databricks. I build PySpark transformations and automated data-quality checks, then publish validated datasets to Snowflake.

I also orchestrate workflows with Apache Airflow and develop dbt dimensional data marts for Power BI and analytical teams. Previously, as a Data Analyst at Key Bank, I built Snowflake datasets and Power BI dashboards for customer and transaction reporting.
