Senior Data Engineer at WellBe Senior Medical building event-driven AWS clinical data pipelines and FHIR-aligned analytics assets.

Message

At WellBe Senior Medical, I own the AWS data platform behind clinical decision support and near-real-time care alerting. I build event-driven ingestion with EventBridge and Kinesis, and process clinical and claims data into curated S3 datasets for analytics.

At Point32Health, I led the migration of provider and claims data flows from legacy on-premises jobs to AWS. I also established Snowflake alongside the S3, Glue, and Athena data lake, enabling analysts to query commercial, Medicare, and Medicaid data.

Across healthcare, retail, financial services, and aviation, I’ve built and supported production ETL and cloud data platforms. My work has included healthcare data quality and CMS audit readiness, enterprise integrations, and high-volume warehouse pipelines.
