Architect-led Azure governance and security, with hands-on delivery.

Arrow pointing right

I’m Petri Hooli, an infrastructure and security architect who cares about doing the work properly. Real work, not corporate noise.

I’ve spent years as a senior IT infrastructure architect, delivering Azure implementations, network solutions and hybrid architectures for large enterprise customers. In those projects I’ve owned the overall delivery — architect, project manager and accountable lead — across the full lifecycle: proposal, design, implementation, go-live, production handover and ongoing operations.

There’s no need to sound polished or corporate. What matters is clarity and honesty. If something doesn’t make sense when you read it back, it probably doesn’t make sense in practice either — and that’s usually a sign there’s more work to do.

Good solutions don’t need hype.

One person, accountable for the whole delivery. I act as the architect, the project lead, and the one responsible for the result — from proposal and design through implementation, go-live, handover and day-to-day operations. When a project needs more hands, I bring in trusted partners.

I focus on long-term results: securing Azure, running it smoothly day to day, and keeping it working as the environment grows.

I think beyond quick wins and focus on work that holds up as things change.
