About Me
Security-First AI Development
I build secure AI systems. As a former CISO, I've seen too many companies rush AI adoption without considering security implications.
That's why I created TopFlow—an open-source platform demonstrating security-first AI patterns. It's not just code; it's a reference architecture for building AI systems with security baked in.
Today, I work with security teams and enterprises helping them navigate AI safely. Whether it's architecture reviews, compliance automation, or team workshops, I focus on making secure AI the default, not the exception.
