I build AI platforms and developer programs

Over the last fifteen years, I've helped build and scale developer ecosystems for highly innovative platform companies including Intel, Arm, NVIDIA, Saga, and Anza, before founding my own company, Verafy.ai. I believe deeply in the power of developers: understanding the most innovative creators and finding new ways to inspire and empower them to build their visions.
