What I'm looking for

I'm looking to build reliable, governed data solutions that solve real business problems, improve data quality, and help technical and business teams make better decisions.

I've built data engineering and governance solutions at Amgen and on a state government payroll and HR modernization program. I design ETL pipelines, data migrations, semantic models, and governed analytics using Databricks, Pentaho, SQL, Python, and PostgreSQL.

At Amgen, I improved geospatial data accuracy by approximately 40%, automated pipeline monitoring to save 8 hours per week, and reduced issue detection time by approximately 50%. I've also established end-to-end data lineage standards that reduced investigation time by approximately 30% and improved audit readiness.

Earlier, I supported real-time manufacturing data ingestion, Hadoop administration, enterprise application development, and database engineering. I enjoy turning complex requirements into practical, reliable data solutions that help teams make better decisions.
