// Meet the engineer
I build the systems that decide whether a request is a real customer or an attacker — and I spend my free time learning how to break them.
I'm now a cloud security engineer at Illumio. Before that, at Fortinet, I helped launch FortiGuard Advanced Bot Protection: hardening client-side telemetry with WebAssembly, designing AI-powered fraud rule engines in Go, and scaling the backend by up to 900%. Earlier I worked on identity security at American Express and bot defense at F5/Shape Security.
Outside the day job I run Lambda Hackers, an indie game studio, consult through Excelsior Ops, and get hands-on at DEF CON.

Add a short description: hardware/software used, the RF technique, and the controlled environment it was tested in.
Short description of the finding, exploit, or methodology used.
The village or challenge, the charger protocol targeted, and what you demonstrated.
The card type, the tools used to read and clone it, and the result.
The scenario or competition, the pretext used, and what you learned.
The lock types attempted and the techniques used.
All work performed under proper authorization and scope. Devices and techniques shown were tested only on owned hardware in isolated, controlled environments — never against third-party or production networks.
