Summary

Snowflake Solution Architect with 25+ years in enterprise data and architecture. Makes the consequential Snowflake AI, security and data decisions with clients, then delivers them: platform foundations, RBAC and identity, live Cortex AI capabilities and AI cost governance, with reusable patterns the client's own team keeps. Combines senior advisory with hands-on implementation, with measurable results — including a data-sharing redesign that saves an asset-management client approximately $2M a year.
