i build systems that stay calm under pressure. i care about security, infrastructure, and things that are hard to corrupt. i live in the terminal and fall into rabbit holes for a living. past lives include shipping an ai email indexing pipeline at a yc'23 company, finding a sql injection in rice.edu at 17, and building developer tooling that people actually use. if i'm not coding, i'm obsessing over mechanical keyboards or reading about distributed systems.

rice.edu security audit

independent · age 17

found a sql injection flaw while learning security. dumped the duplicated database, documented the vulnerability, and sent a full audit with fixes. no malicious intent — just curiosity. first time a bug felt real.
