I'm a student in Korea and I run the Bitbang Computer Science Lab (BiCSL). I work on security and machine learning, including acoustic side-channel attacks on Korean Dubeolsik keyboards (KDAA) and data poisoning in multilingual language model pretraining.

I also build programming languages and developer tools, such as Cotton, a new language implemented in Rust, and Thrubase, a local tool that helps people understand AI-generated codebases.
