Rewrote an entire post-silicon debug toolchain months ahead of schedule at a savings of $3 million per day according to corporate calculations.

Specializes in creating state-of-the-art code generators such as a highly sophisticated reverse code packer for a custom VLIW CPU that builds itself based off of parsing the specification.

Accomplished at writing Directed-Random testbenches which provide over 95% of coverage.

Great at novel approaches to breaking things, which is why I've posted bugs in almost every tool I've used, including established tools such as compilers, linkers, shells, assemblers.

Designed/implemented custom shipping operations algorithms as a test pilot for DHL, accomplishing an order of magnitude improvement in runtime and savings.
