I'm a security engineer at Apple working on iCloud and Apple Cloud Services.
I used to be a Principal Security Engineer at Amazon Web Services.
I used to work in AWS Cryptography and was primarily responsible for Amazon Trust Services, their public CA. My old group also owns AWS CloudHSM, AWS Key Management Service, and some new things. Previously I worked on EC2 and have dabbled in various other parts of AWS.
Of course we are hiring, so please send me an email if you are interested in applications of cryptography, public key infrastructure systems, hardware security modules, or similar things.
