At Hubtel, I've provided first- and second-line support for hardware, software, and network issues while maintaining computers, routers, switches, firewalls, and wireless access points.
I've diagnosed LAN/WAN connectivity issues across TCP/IP, DNS, DHCP, Wi-Fi, and VPN services, supported upgrades and network expansions, and worked with vendors to resolve complex incidents. My preventive maintenance improvements reduced equipment downtime by 90% and maintenance-related problems by 80%.
Earlier at AT&T Telecommunications, I supported customers and internal teams with IT equipment, servers, network devices, outages, and service interruptions.
