About

I help protect people and platforms at scale by transforming intelligence into action. My experience spans Big Tech, financial services, and government, where I’ve built abuse detection and analysis capabilities that safeguard billions of users, global enterprises, and national infrastructure. Driven by a focus on intelligence, detection, and enforcement, I’m motivated to make the digital world safer for everyone.
