I'm Chao Tan — data governance and privacy engineer at Snowflake, where I built the classification platform that auto-tags sensitive data at scale. 18 years in the craft, from eBay to HSBC to Amazon Alexa to here. I write about data governance, AI system security, performance engineering, and the honest parts of a career in tech.
