The thread through it all
Put the work where it happens, and keep the decision with the person.
At the desk, on the table, in the gym. The AI proposes. The human decides what ships.
Joshua Silva Maniche
Rotterdam, NL
AI that lives in the room, not on a screen.
I build for smart glasses and physical hardware: lenses, apps and the agent teams that make them.

Lens
Creative developer from Rotterdam. I bring AI into the physical world.
I build for smart glasses and real hardware: Snap Spectacles and Meta Ray-Ban Display. Lenses, apps and the tooling around them.
I run AI agent teams to build faster, and I keep the decision with the person. Two first places and a second in Snap's Spectacles Community Challenge, and a safety product in production.
joshualevi is Joshua plus Levi, the AI cofounder I run alongside me.
