At Ptra Sistemas Informáticos, I support Windows 10/11 and administer Windows Server 2016–2022, resolving account, domain, and network issues. I also provide basic Microsoft 365 support and help users with Wi-Fi, VPN, and PC setup.
Previously, I was Responsable del Área de Sistemas at La Mundial de Seguros (Grupo Cesce), where I administered Windows Server, managed security policies and backups, and supported networks and business applications. I also prepared technical reports for management and regulatory bodies.
