Salvatore Difranco

Software engineer who ships real products — and works with coding agents in a measured way.

In production rather than in a sandbox — civic software running for households in Sicily, a macOS application shipped as a download people install. The part I care about is the part where it goes live and stays up.

The agents are run to a written method — a spec first, tickets after it, one fresh context window each, and nothing committed before it has been reviewed twice.
