I’m Victor Ola T. Every Field Note on this site is signed Captain O, because that is what people call me, so it is the name I answer to here. This page is who that is, and what the name is worth.
I did not come from computer science. I came from the cockpit. I flew helicopters professionally for a few years, and somewhere in those years I decided the runway I actually wanted was in the cloud. I taught myself, I broke in, and I never looked back. I still fly, for fun now. Nine years in enterprise IT later, six of them entirely on Azure, I work as a Senior Azure Cloud & DevSecOps engineer.
The checklist habit comes from flying. A pilot does not trust memory before take-off; a pilot reads the card. That is the discipline I bring to the classes and to the notes: a claim is either checked against the source or it is not on the page.
It means I set the brief, I decided what the piece had to get right, and I checked what it says against Microsoft Learn and against what I have run myself. Where a note draws on my own incidents, migrations and mistakes, it says so. Where it is teaching a service I would not run in production without checking a limit first, it names the limit and the page that states it. If a note is wrong, that is mine to fix, and the changelog on this site is public.
The notes lean toward the things I actually do: Azure identity and governance, tenant-to-tenant migrations, infrastructure as code, pipelines, and the security posture around all of it. They lean away from head terms Microsoft documents better than anyone can, because pretending otherwise is a waste of your time.
People ask what I hold, so here it is, and then we can move on. An MSc in Cybersecurity and a BSc in Information Technology. CompTIA Security+, CySA+, PenTest+, Network+ and A+. ISC2 CC and CISM. ITIL v4. Linux Essentials. And PSM. They are real, they took work, and not one of them is the reason anybody hired me. The things I had built were.
The forty-two classes of the CAMPUX Cloud Engineering Bootcamp, reverse-engineered from real job postings rather than an exam outline. The public labs library, fourteen labs with the CLI and the infrastructure-as-code side by side, open on GitHub. A deployable retail capstone that runs the same container on App Service and on AKS. And Keel, a secure Azure infrastructure-as-code framework, which lives on its own now.
Professional history is on LinkedIn, code is on GitHub, I cross-post some notes on dev.to and Hashnode, and the consultancy side of the work is at victor.thomsup.com. Learners write to me through the community board; that is the fastest way to get a correction in front of me.
