What I'm looking for

I'm seeking an IT Project Manager role where I can use my infrastructure, documentation, security, and leadership experience to manage IT projects precisely, deliver quality outcomes, and foster collaboration across teams.

I'm currently managing Linux infrastructure at Stanbic IBTC, supporting secure, highly available environments across Kubernetes, OpenShift, Helm, storage, web, database, and application servers.

Previously at AIICO Multishield, I led Windows Server, hybrid Exchange and Office 365 administration, VMware virtualisation, SAN/NAS storage, and IT security improvements. I collaborated with cross-functional teams to align infrastructure with business objectives and resolve incidents quickly.

At Flour Mills of Nigeria and Clear Vision Global Concept, I designed and supported VMware, Hyper-V, Windows Server, Microsoft Exchange, SAN/NAS storage, Linux systems, and security controls. I also automated administrative work with PowerShell and conducted system audits for compliance.

I'm building on my systems administration and management experience to move into IT project management, delivering quality IT projects through precise execution, documentation, security, and team collaboration.
