Built Sentry for the Flowstep challenge, a home AI that watches for gas leaks, overloaded circuits, and fire risks before they turn into an emergency, instead of just alerting you after the damage is done.

What actually got me was building this entirely inside Flowstep - went from a rough idea to a full multi-screen, clickable prototype just by describing what I wanted, then refining it screen by screen on the canvas until it actually felt real. No design tool switching, no exporting back and forth, just prompt, see it, adjust, repeat. Sentry
