Nelson Chinedu
Odigili
IT Field Engineer / Network Infrastructure / Technical Support
I diagnose, install and support technology across the endpoint, operating system, network and physical site. My background combines over ten years of computer and mobile-device repair, field engineering, networking, CCTV and practical customer support.
01 · Professional profile
A broad technical foundation, now focused on infrastructure.
I am a hands-on IT Field Engineer and support technician with experience developed through repair benches, customer premises, independent service work and structured homelab practice.
I began with computer and mobile-device diagnosis and repair, learning to isolate faults rather than replace equipment without investigation. I later expanded into routers, wireless networks, CCTV, recording systems and onsite installation. My current field engineering work has strengthened my ability to follow technical instructions, work independently at client sites, communicate with users and document completed work.
My infrastructure development now covers Cisco IOS and MikroTik RouterOS, VLANs, subnetting, DHCP, DNS, NAT, VPNs, switching and routing labs, Windows Server, Active Directory, Microsoft 365, Entra ID, Linux services, virtualisation and network security appliances. I use real equipment alongside VMware, EVE-NG and Cisco Packet Tracer so that configuration practice includes physical cabling, endpoint behaviour and genuine troubleshooting.
I am particularly suited to roles where an engineer must look beyond one layer of a fault: checking the user’s symptoms, endpoint, drivers, operating system, cabling, switch port, addressing, DHCP, routing, firewall rules and connected services before reaching a conclusion.

04 · Practical homelab
A working environment for systems, networks, voice and security.
My homelab connects real network hardware, virtual machines, servers, phones and cameras. It allows me to build topologies, create faults, inspect logs, test changes and document outcomes rather than learning only from theory.

09 · Professional interests
Why I continue building.
I am interested in infrastructure that remains understandable and supportable after installation: sensible addressing, clean cabling, controlled access, configuration backups and documentation that another engineer can follow.
My long-term goal is to combine UK field and infrastructure experience with a practical managed IT and electronic-security business serving SMEs and communities. That makes networking, Microsoft environments, Linux services, secure remote support and physical installation commercially relevant to me—not merely subjects for certification.
I also retain the repair-first mindset developed through years of break/fix work: investigate the cause, preserve useful equipment where sensible and recommend solutions based on the actual fault.
