I build security products that make AI systems and cloud platforms safe-by-default—especially in regulated, high-stakes environments.

Most recently, I’ve focused on securing Google Distributed Cloud and delivering Security-as-a-Service capabilities for critical infrastructure, including enabling on-prem AI adoption in sensitive settings. I’m known for translating complex risk into clear product direction (PRDs, reference architectures, threat models) and driving alignment across engineering, security, and customer stakeholders.

Earlier in my career, I led XDR/MDR and endpoint/platform security products—so I bring a pragmatic “platform + operations” lens to AI security and enterprise adoption.
