Executive Perspective

“I do 'all the things'.”

In security engineering, resilience isn't built in silos. With over 30 years of disciplined hands-on experience—starting as a US Army Paratrooper and NCO managing tactical digital communications and cryptographic systems—my approach unites low-level packet analysis with high-level infrastructure design and modern AI automation.

Whether deploying global perimeter defenses, managing high-severity incident queues, or architecting agentic AI tooling with Anthropic frameworks, security is an end-to-end discipline.
