What I'm looking for

I'm looking to lead cloud data platform work where I can modernize pipelines, improve data quality and governance, mentor engineers, and partner closely with stakeholders on healthcare, financial services, or insurance analytics.

At Leap Metrics, I lead cloud data platform architecture across healthcare, SaaS, and financial services, consolidating fragmented reporting into governed ingestion-to-serving pipelines. I build ETL/ELT, CDC, and streaming pipelines with Python, PySpark, Databricks, Airflow, dbt, Kafka, Kinesis, AWS S3, Delta Lake, and Snowflake.

Across SmartAsset, CareSet, and Capital Technology Group, I've modernized legacy ETL, integrated claims, eligibility, provider, and clinical data, and built trusted warehouse and lakehouse layers for analytics teams. I also lead architecture reviews, mentor engineers, and partner with data scientists, BI teams, security, and business stakeholders to deliver HIPAA-aligned data products.
