Applying Data Reliability Engineering principles I pioneered at Hitachi to drive data reliability, lineage visibility, and audit-ready design supporting analytics, regulatory reporting, and AI use cases across Fiserv's financial platforms serving 100+ million consumer accounts.

Led critical digital transformation for Republic Finance, one of the largest consumer installment loan providers in the United States ($1.4B+ portfolio, 360,000 customers, 260+ branches). Designed and deployed AI-powered fraud detection system achieving 55% reduction in fraud losses, 70% faster investigations, and 40% fewer false positives, now adopted as company-wide standard. Led enterprise migration from SQL Server to Snowflake, implementing Data Reliability Engineering frameworks that improved data quality metrics by 30% and ensured regulatory compliance. These fraud prevention methodologies have broader applicability across the consumer lending industry.

Served as founding architect of Data Reliability Engineering (DRE) within Hitachi Application Reliability Centers, pioneering a discipline now recognized and adopted globally. Developed frameworks for self-healing data pipelines, automated data quality monitoring, AI-powered observability, and cloud-native governance that were integrated into Hitachi Lumada platform. These frameworks are now independently deployed by Fortune 500 organizations including Disney Parks (predictive maintenance), Toyota, Wells Fargo, UCLA, Yamaha, and Suntory for predictive maintenance, digital payments, and operational optimization.

Led data architecture transformation for Texas Capital Bank ($28B assets, named Best Regional Bank 2024 by Bankrate), designing cloud-based digital onboarding platforms, data governance frameworks, and regulatory compliance systems.
