About Me

The engineer behind
the infrastructure

I'm an IT Infrastructure Engineer with over 8 years of hands-on experience supporting enterprise systems, network infrastructure, and cybersecurity operations across Nigeria. My work sits at the intersection of hardware engineering, network architecture, and security — I don't just maintain systems, I design environments built to last.

I've led deployments of 250+ workstation environments, configured Cisco switching and VLAN segmentation at scale, integrated solar-backed power infrastructure for critical uptime, and delivered security training that builds institutional awareness from the ground up.

Beyond the technical work, I've held leadership positions — as ICT Manager and as Chairman of the IEEE ComSoc UNIZIK Chapter — because I believe engineering impact comes through people as much as technology. I'm currently based in FCT-Abuja and actively seeking my next challenge.
