SELECTED WORK
WHAT I DO
01 / AUDITS
Security Audits
Wireless, embedded, and web systems tested the way an attacker would — so gaps get fixed before they're found.
02 / FIRMWARE
Embedded Firmware
Detection and defense firmware for ESP32, M5Stack, and custom nodes — running right on the metal.
03 / MOBILE
Mobile & Full-Stack
iOS, Android, and web apps — backed by a bachelor's in mobile development.
04 / OPEN SOURCE
Open Source
Building and contributing to FOSS since 2010 — tools the community actually runs.
ABOUT
