Hardware and privacy security
Security, privacy and AI engineer and hardware security researcher. I've worked on Apple platforms since 2007, and I'm best known for research into Apple's T2 security chip with Team t8012.
Previously at Meta, Coinbase, Dropbox, Uber ATG, Jet.com, Bloomberg and Microsoft. Most of what I build is open source.
