At Spark Advisors, I architect enterprise healthcare data platforms that unite 25+ EHR, claims, laboratory, pharmacy, and operational sources for clinical, operational, and analytical use cases.

I've delivered HIPAA-compliant ETL/ELT pipelines with Azure Data Factory, Databricks, Python, SQL, and Palantir Foundry, automating millions of healthcare records. My lakehouse architecture improved analytics scalability by 35%, while pipeline tuning delivered 25–30% faster execution and reduced healthcare data latency from hours to minutes.

Previously, I built 100+ automated ETL/ELT workflows at LangChain and high-volume Kafka pipelines that cut analytics latency by 50%. At SentiLink and ReversingLabs, I engineered distributed Spark pipelines, cloud data lakes, integrations, and production deployment practices for large-scale enterprise data.

I combine hands-on engineering with architectural ownership, building governed data products with lineage, quality controls, PHI/PII protection, and reliable access for reporting, analytics, and machine learning. I also mentor engineers and translate healthcare and business requirements into production-ready cloud data solutions.
