    Achievements

    I studied CS and ran a team at Oracle. Then I co-founded NetGravity and took it public in the dotcom boom. I shepherded my second company through the 2008 crash and ultimately to profitability and a successful acquisition. Along the way I have been a VC for over a decade, sitting on boards and helping with acquisitions. Now well down the crypto rabbit hole and writing code again, full circle.
