Senior Data Engineer at Change Healthcare building HIPAA-compliant pipelines for claims and healthcare data.

At Change Healthcare, I design HIPAA-compliant data pipelines for claims, member, provider, and healthcare operational data. I use Python, PySpark, Databricks, and SQL to process and publish data for analytics and reporting.

I build batch and near real-time workflows and reusable transformation frameworks, and orchestrate production pipelines with Apache Airflow. I also develop dbt models and automated data quality checks to help deliver consistent, analytics-ready datasets.

At Cardinal Health, I developed data pipelines processing 200+ GB of healthcare and pharmaceutical data daily. I created Airflow workflows and Snowflake data marts, and optimized selected workloads, contributing to approximately 25% improvement in processing performance.

Earlier, I developed ETL workflows for financial and operational data at Bank of America and supported SQL Server and Oracle databases at Walmart. I hold Snowflake SnowPro Core, AWS Certified Data Engineer – Associate, and Microsoft Certified: Azure Data Engineer Associate certifications.
