david@homepage:~/david$cat about.md

Founder & CTO of RollDeep. Fractional CTO for WorldFit, CrewChamp, and the Logos Project. Formerly Reddit, the New York Times, and the Coral Project.

If you have a hard problem in marketplaces, civic tech, news infrastructure, or human-flavored AI — I'd like to hear about it.
