I help people build secure software. I lead a team of the most talented security experts in the world at Security Innovation to perform security assessments and help our customers reduce their risk against the ever-present threat of hackers and other ne'er-do-wells.

I started a non-profit, Technically Learning, a few years ago with the help of some friends to help kids, particularly girls and minorities, get excited about the STEM fields. Technically Learning recently merged with code.org an amazing new non-profit looking to bring Computer Science to all public schools in the US.
