Sr. Specialist Solutions Architect — Healthcare & Life Sciences | Databricks

🚀 About Me

I’m a Sr. Specialist Solutions Architect at Databricks, focused on Healthcare & Life Sciences, with deep specialization in Data Warehousing and Data Engineering. With over 25 years of experience in software development—and more than a decade dedicated to large-scale data systems—I help organizations design and implement production-grade lakehouse architectures that unify analytics, governance, and AI on a single platform.

My work centers on helping customers modernize legacy data platforms by adopting the Databricks Data Intelligence Platform—leveraging Lakeflow for end-to-end data engineering, Unity Catalog for unified governance, and Serverless SQL Warehouses for high-performance analytics. I specialize in designing scalable Medallion architectures, implementing real-time and batch pipelines, and enabling teams to move from fragmented toolchains to a cohesive, governed data ecosystem.

Prior to Databricks, I spent nearly a decade architecting data platforms in healthcare and energy — as Principal Big Data Architect at CodaMetrix (building their Lakehouse Intelligent Platform on Databricks and Kafka), Principal Data Engineer at HealthVerity (leading a full platform re-architecture from legacy EMR to Databricks), and across five years at Enverus designing data lake and analytics solutions for the Oil & Gas industry using Spark, Delta, and Azure. Before pivoting to data, I spent 10+ years as a software engineer and architect building high-scale web platforms at companies like SocketLabs and Comcast.
