What I'm looking for

I'm looking for a role where I can resolve network and IT incidents end-to-end, strengthen FTTH, NOC, enterprise networking, and Microsoft 365 capabilities, and contribute to reliable, customer-focused service delivery.

I'm supporting FTTH backend operations at MTN Nigeria, monitoring network performance, managing OLT/ONT services, resolving provisioning and connectivity issues, and configuring WiFi extenders for last-mile optimization.

I've also delivered enterprise WAN, firewall, routing, switching, and Layer 2/Layer 3 troubleshooting with DigitalCast Technologies, collaborating remotely with Verizon engineers. In MSP environments at Pacific IT Support, I provide Tier 1–3 support across Microsoft 365, endpoints, firewalls, backup systems, RMM tooling, documentation, and SLA-driven service delivery.

My background includes NOC operations at TIZETI and FiberOne Broadband, network installations at Telcroft Technologies, and Exchange Online support at Tek Experts. I focus on fast incident resolution, clear documentation, reliable network performance, and customer-focused technical support.
