What I Do
Security Audits
I test wireless, embedded, and web targets the way an attacker would, from inside and outside the network. You close the gaps before anyone else finds them.
Embedded Firmware
I write detection and defense firmware for ESP32, M5Stack, and custom nodes. The code is lean and runs close to the metal.
Mobile & Full-Stack
I design, build, and ship iOS and Android apps and the web services behind them.
Open Source
I build free tools for spotting drones, trackers, and surveillance gear, and keep them maintained in public.
