Microsoft-only, on purpose
Azure and Microsoft 365 are the whole practice, not two lines in a longer list. We'd rather have seen your exact problem before than hold a partner badge for everything.
About Caellix
Small by design. Senior by default.
Caellix is a Microsoft practice built around one idea: cloud projects go right when the people who design them also build them — and then hand them over. No juniors learning on your invoice, no slide-deck consulting, no dependence sold as a service.

The rules we run on
Decided once. Not renegotiated per project.
Senior-only, founder-led
The founder leads every engagement and stays hands-on. When a project needs more hands, they're senior engineers employed by Caellix — not a delivery pyramid.
Ready for pressure
The real test of an environment comes during growth, incidents, audits, releases, and people changes. Caellix designs for those moments, so the platform behaves predictably when the business cannot afford confusion.
Documented, or it didn't happen
Decisions, configuration, and runbooks land in your repository as we go. Handover isn't the last milestone — it's a constraint on every milestone before it.
Who you'll work with
Founder-led — literally.
I founded Caellix after seven years of building and running Azure and Microsoft 365 environments — architecture, administration, security operations, and FinOps — and 10 active Microsoft certifications along the way. Long enough to see the same pattern everywhere: the expensive problems were never about missing technology. They were about environments nobody fully understood anymore.
So Caellix works the way I always wished suppliers did. I'm on every project personally, I bring in senior engineers employed by Caellix when the work needs more hands, and everything we build is explained and handed over. And if your problem isn't one we're right for, I'll tell you on the first call.
How we work
From first call to handover. No theatre.
The same four steps whether you buy a scoped assessment or an end-to-end build — only the depth changes.
-
Scope
One call, then a written proposal.
A working session with an engineer, then scope, price, and deliverables in writing — whether it's a focused audit or a full build. You decide with a document in hand.
-
Assess
Evidence before promises.
Every engagement starts from what's actually there: estate, configuration, spend, or security posture. You get a written read and a prioritised backlog — for audit engagements, this is the deliverable.
-
Deliver
End to end, in visible increments.
From architecture decisions to a working, documented platform. Progress demos, decisions recorded as they're made, and everything landing in your repository as we go.
-
Hand over
Your team runs it.
Runbooks, documented decisions, and a clean exit. Every engagement is designed to end — and to end well.
