Cloud
Cloud that is designed, secured, and paid for on purpose. We cover public, private, and hybrid architecture, migrations that don't break production, workload protection, and the cost discipline that keeps a cloud bill from quietly doubling. The goal is the same one we bring to client engagements: resilient systems you can reason about.
What cloud covers
Architecture & migration
Public, private, and hybrid design, landing zones, and migrations that move production workloads without downtime.
Cloud security & posture
CSPM/CNAPP, workload protection, and identity hardening across AWS, Azure, and GCP so misconfigurations are caught before they're exploited.
Cost & operations
Right-sizing, FinOps discipline, and day-2 operations that keep both the bill and the risk under control.

Managed ITThe Deploy That Fails Because of Your Git Email
A push lands, the build never starts, and nothing in the repository explains why. Hosting platforms gate deploys on the commit author identity, and a one-character domain typo is enough to stop a release.

Microsoft Entra Conditional Access is the most useful security control most organisations own and never configure properly. A starting policy set, in the order to deploy it, with the break-glass account that keeps you in.

Most organisations overspend on Microsoft 365 in four specific, findable ways. None of them require a renegotiation — just an afternoon with the admin centre and a willingness to act on what it says.
