Led data modeling and architecture for SaaS catalog and pricing intelligence systems spanning 16k+ active companies and 28k+ products.
Designed agent-driven, human-reviewed data workflows and a pull-request-style system for safely evaluating and executing changes to production data.
Managed the technical relationship with extraction partner Extend, influenced vendor product direction, and led a cross-functional team that scaled into three specialized teams.
Retained through Vendr's 2026 acquisition by Vertice as a subject matter expert for acquired technology and data assets I helped develop.
