01 / about

Building, breaking,
learning, shipping.

Born in 2010 — building Android apps, AI agents and security toolkits, mostly at 2 AM, mostly just to see if it works. Chinese / English, Beijing based, open-source driven.

“The only way to learn a new programming language is by writing programs in it.”
— Dennis Ritchie
