I have spent 30 years in technology including nearly a decade as a startup cofounder, a product director at Google, a long-time angel investor, and most recently 6 years as the head of Block's Spiral initiative. At my first startup I created a clean-room Java virtual machine for embedded and real-time systems then managed 2 dozen software engineers building out the product. At Google I led the mobile Google Maps team growing from 0 to a billion users. I then helped create and lead the Google Glass team within Google X. My contributions to bitcoin include helping create Presidio Bitcoin, open source software projects including LDK, BDK and the BDK Foundation, and Stratum v2 reference implementation project, the bitcoin design community, the bitcoin consensus analysis project, COPA including defeating Craig Wright, Bitcoin Optech, ₿trust, Block’s mining business, and the PBJ show.
