Independent IT consultancy for organizations that run on Microsoft
Cloud, security and architecture decisions that still hold up years later.
What Oxygen IT does
Six kinds of work, delivered by one senior consultant.
Cloud migration and Microsoft 365
Moving datacentres to Azure and setting up Microsoft 365, identity and networking. The foundation everything else runs on, done so it does not need redoing.
Architecture and advisory
Platform strategy, data and integration design, and decision records that explain the trade-offs in language management can act on.
Security advisory
Secure-by-design cloud environments, policy that is enforced rather than agreed, patching that actually happens, and honest business cases for security tooling.
AI-assisted engineering
Bringing AI coding tools into an organization with guardrails: who may build what, where it runs, and who signs off. Oxygen IT builds with the same tools.
Application hosting
Running business applications on a hardened, managed platform, including applications built with AI tooling that need a proper home in production.
Architect on assignment
A senior architect for an agreed number of hours per week, on a project or retainer basis, when the expertise is needed but not the headcount.
How Oxygen IT works
- Permissions over promises.
- What a system may reach is enforced by access rights, not by agreement.
- Measured, not assumed.
- Costs, risks and benefits come from actual data, and vendor claims are labelled as vendor claims.
- Reversible by design.
- A good decision has an exit path, and a move between platforms should be a redeployment, not a migration project.
- Humans gate what machines generate.
- AI drafts; a person approves before anything reaches production.
- Trade-offs written down.
- Every recommendation records the alternatives and why they lost, so it can be challenged later.
About Oxygen IT
Oxygen IT B.V. is an independent IT consultancy based in Culemborg, founded in October 2021. The work is delivered by Patrick van der Wal, who has worked in IT since 2002 for a wide range of organizations, from mid-sized companies to large enterprises, and holds the CISSP, CCSP and Azure Solutions Architect certifications. Every assignment is handled by the same person from the first conversation to the last commit, and Oxygen IT declines work that falls outside what it can do well.
