I've delivered healthcare and life-sciences data solutions for Philips, Novartis, and Liberty Mutual, building Qlik Sense and Power BI dashboards, scalable Databricks and Snowflake ETL pipelines, and optimized SQL workloads.

My work spans clinical trial, patient, lab, genomic, supplier quality, and patient safety data. I've also used Generative AI to reverse engineer legacy applications, document data flows and architecture, and create reusable technical knowledge bases in Confluence.
