Hey, I'm Tosin — an IT Systems Operations Specialist and Azure Cloud Administrator passionate about keeping infrastructure secure and running at full strength. I specialize in identity & access management, cloud operations, and PowerShell automation. Whether it's provisioning 200+ endpoints, triaging security alerts, or building IaC pipelines — this is my work. Take a look around and see what I've built.

HOW I GOT HERE
& WHERE I'M GOING.
"Curiosity turned into a career — once I saw how cloud systems break, I knew I wanted to be the one who keeps them running."

My journey into IT started with a genuine fascination with how systems work and how they fail. Early on I found myself diving into infrastructure automation, identity management, and cloud security — the operational side clicked for me naturally.

That drive led me to pursue certifications that reflect where I operate — the AZ-104 Azure Administrator gave me the technical foundation, CompTIA Security+ sharpened my security mindset, and ITIL Foundation grounded my approach to service delivery. Each was a deliberate investment, not just a checkbox.

Today I bring 3+ years of hands-on experience supporting enterprise infrastructure at Tiatra, Cox Enterprises, and International Tech Solutions — managing everything from 200-user Active Directory environments to daily security triage and PowerShell automation suites that cut manual work by 40%.
