  One of the principal system designers of Crucible, a secure virtualization platform for technologyprotection and system integrity of defense systems. Augmented the eCryptFS stackable filesystem to use NIST-approved algorithms, per-page keying, and page integrity in a private fork. Created command-line utilities to sign and encrypt files in our eCryptFS-derived file format. Wrote and maintains a policy configuration UI in React/Redux and JavaScript. Added support for characterizing hardware and booting using the multiboot2 boot protocol into iPXE for network-booting Xen on UEFI. Maintains a configuration storage network service exposed over HTTP. Maintains a virtual machine and virtual network launch daemon that runs in a Yocto-based control domain for Xen. Show less
