likes computers & math

I secure the blockchain at OtterSec and develop the future of finance at Zellic's Quantitative Research Lab.

I'd like to see as much computer science and pure mathematics as I can. Embedded systems, where programmers have creative freedom over hardware, software, and the bridge between the two, are my favorite.

I currently focus on cybersecurity. As a member of the United States' #1 competitive cybersecurity team, DiceGang, I work with government organizations like the United States AFA, AĆ©roports de Paris, Saudi FCSP, and UAE Cybersecurity Council and blockchain organizations like the Solana Foundation, the Sui Blockchain, and Aptos Labs to make the internet safer.

As an academic researcher, I've done guest lectures on exploitation at the HOPE Security Symposium, Carnegie Mellon University, and EPFL Innovation Park. Check out this piece on exploiting one-byte writes in standard libraries!
