Professional summary

I am a Technical Support Engineer with hands-on experience in IT support, network troubleshooting, Linux administration, Windows Server administration, and infrastructure operations.

I have supported day-to-day IT environments through system monitoring, operational checks, backup verification, patch deployment, asset management, and server and CCTV monitoring. I am experienced in resolving user-access and infrastructure-related issues.

My networking knowledge includes TCP/IP, OSI, IPv4/IPv6, subnetting, DHCP, DNS, VLANs, STP, NAT, RIP, OSPF, SSH, EtherChannel, PAgP, and LACP. I have configured Cisco and Dell switches, routers, wireless access points, and related network devices.

I have practical Linux administration experience with RHEL, BIND DNS, Apache, FTP, NFS, Samba, iSCSI, LVM, user and group administration, ACLs, troubleshooting, and log analysis. I also have experience with Windows Server 2016, Active Directory, Group Policy, DHCP scopes, and NIC Teaming.

I have worked with technical support and security tools including Palo Alto Firewall, Microsoft Defender 365, ManageEngine, Freshdesk, CrowdStrike, Veeam, and Zendesk. I also have exposure to VMware, Hyper-V, VirtualBox, AWS, Azure, and Google Cloud concepts.

I am willing to work across global time zones and am seeking a Technical Support Engineer role where I can provide reliable technical assistance, resolve infrastructure issues efficiently, and contribute to stable IT operations.
