03 // Trajectory / CV

Persio Pucci

Networks, operations, and the judgment that comes from troubleshooting them. Today I bring that experience to independent software work and project controls.

I define the problem, direct AI agents through implementation, and assess the result. My background runs through internet access, backbone networks, managed services, technical leadership, and security.
