 Profile Firmware & IoT Engineer 
 
I write firmware for machines that are not allowed to fail quietly.
 
 
 
I am a Firmware & Product Engineer at Anedya Systems. Right now that means a smart RO purifier, a gateway reading PLC data over Modbus, data loggers going into mass production, and a libpeer port that makes the Beken BK7258 do real WebRTC. Before that I wrote stripper controller firmware for an 18 MeV medical cyclotron at the Variable Energy Cyclotron Centre, and built KryOS, a Buildroot Linux distribution that watches vaccine cold storage on a Raspberry Pi 4.


The common thread is recovery. Getting code to work is the easy half. Getting it to come back after a stuck I2C line, a dead node, or an hour with no network is the actual job.


Most of what I know came from breaking something on a bench and reading the datasheet afterwards.
