Rocco D'Affuso

I build AI things at night, just to see what happens.

Builder & explorer. Mostly after dark.

Local-first AI tools, native apps, and useful web experiments. Built after work, driven by curiosity, and shipped for people to use.

    Dum-E

    Robotics · design in progress

    A desktop robot I'm designing to handle everyday objects, starting with cables and chargers. Four fingers, an upgradeable build, and a lot of mechanical iteration.

    How the memory loop works

    one session becomes context for the next
    AI session

    The work begins with a concrete task, source files, and decisions made in context.

    The short version

    I'm Rocco. By day I work on enterprise retail systems. After dark I build local-first AI tools, native apps, and useful web experiments. Some ship as open source, including BrainBar, Corewise, and an AI memory skill. Others become focused products such as Pulse Vitals, NettoLab and StimaLavori. This page keeps the projects, experiments, and work behind them visible. If that sounds like your kind of thing, come along.
