Principal Data Engineer at Mutual of Omaha Mortgage leading an enterprise Databricks migration and automating migration validation with Claude agents.

Message

At Mutual of Omaha Mortgage, I’m the technical lead for an enterprise Databricks migration across SQL Server, Snowflake, Microsoft Fabric, and Databricks. I built a reconciliation app with Claude agents that automates migration validation and root-cause analysis.

I took the largest dataset in the environment—about 250 tables and 10+ TB—from concept to production on Snowflake. I also architected a Microsoft Fabric lakehouse integrating 40+ operational systems into data products.

As Data Warehouse Administrator, I replaced an offshore team within 90 days, saving about $120K a year. Earlier at Mutual of Omaha Mortgage, I modernized analytics, improved data process efficiency by roughly 300%, and delivered 40+ Power BI dashboards and semantic models.

Before that, at Ceridian, I built a C# support application and reports for platform health and customer operations. My work also includes credit-data integrations at Informative Research and finance operations, reporting, and billing systems at Genesis HealthCare and Hallmark Rehabilitation.
