About

$ whoami

I look at security as a system, not a stack of tools. Seven-plus years in IT infrastructure, three in security — and I've seen how a single misconfigured policy can snowball across an entire fleet. I've protected environments with over 1,000 endpoints and engineered policy across a fleet of next-gen hardware firewalls.

I'm driven by curiosity and a systems-level view of how things fit together — from the infrastructure that powers an organization to the threats that target it. I'm currently focused on cloud architecture and generative AI, and I approach every problem with an eye toward the bigger picture: not just fixing what's broken, but understanding why it broke and how to make the whole system more resilient.
