CALOGERO TIRANNO
@calogerotiranno
Senior IT Technician specializing in Windows systems, service management, and desktop support.
ItalyWhat I'm looking for
I’m an IT Technician with over 15 years of experience in technical assistance, desktop management, and Windows systems administration for major public (Comune di Milano, ASP Catania) and private (British Telecom/Atlanet, Accenture) organizations. I specialize in problem-solving in mission-critical environments and in providing first and second-level support that keeps services running smoothly.
I’m strongest when I can manage end-to-end IT operations and coordinate teams. At ASP Provinciale di Catania, I completed complete IT management of a Covid-19 vaccination plan (workstations, networks, printers, and vaccine registration software) and coordinated a team of 4 operators, reducing onboarding time from 30 to 10 minutes.
Previously, I managed the IT platform for the City of Milan, coordinating troubleshooting interventions on > 5,000 workstations and implementing ITIL procedures for the Service Desk, reducing average ticket resolution time by 20%. I also trained new operators on ticketing tools (e.g., Siebel), and today I’m additionally working as an AI Trainer, reviewing and evaluating Italian AI outputs for quality and consistency.
