I am a Systems, Network, and Security Administrator with over 6 years of hands-on experience supporting, securing, and maintaining IT infrastructures for businesses and professionals. I specialize in keeping systems reliable, networks stable, and data protected, while solving real problems that affect daily operations. My expertise includes Windows Server (2012, 2016, 2022), Active Directory, DNS, DHCP, Group Policy, and user access management. I regularly troubleshoot Office 365 and Outlook issues, handle VPN and RDP connectivity problems, and support Windows 10 and 11 environments. I also have experience with malware removal, NAS servers, video surveillance systems, and business software such as Sage 100c. With a Master’s degree in Cybersecurity, I apply security best practices to system administration, focusing on risk reduction, access control, and system hardening. I value clear communication, fast problem resolution, and practical solutions that match real business needs. My goal is to help clients run secure, efficient IT environments—without unnecessary complexity.
