About Me

Results-driven Embedded & Network Engineering professional with 5+ years of experience delivering firmware, hardware design, and secure communication systems for IoT, ultra-low-power and ultra-low-memory Wi-Fi SoC platforms.

My work on Neutrino - an ultra-low-power ultra-low-memory Wi-Fi SoC involved compressing an entire Wi-Fi security stack (OpenAuth-WEP40-WEP104-WPA-WPA2-WPA3-WPS, MQTT over MBEDTLS, OTA Firmware updates) into just 512 KB RAM. Implemented HW Cryptography on bare-metal system.

I thrive at the intersection of hardware constraints and network security. Currently expanding into network infrastructure design, configuration, and security for critical communication environments, drawing directly from years of low-level protocol work and interrupt-driven architectures.
