About Me

I build things that are fast, efficient and secure, from encrypted LoRa radios and ESP32 firmware to Rust tools, and I talk about them at security conferences.

Hello, I’m Leonardo Lees, a Canadian-American self-taught full-stack developer with a passion for systems architecture, security engineering, and embedded software.

I have been writing code since 2018. I am a quick learner who is always eager to learn new skills and hone the skills I already possess.

Outside of coding, I like to play guitar, mess with circuits, and dabble in cinematography.
