The Case Centre: fifteen years of infrastructure nobody had to think about

Sole IT administrator for an international, not-for-profit publisher serving business schools worldwide. One person, every layer — from the patch panel to the cloud bill — for over fifteen years. The achievement isn't any single project; it's that IT was never the thing standing in the company's way.

01The job under the job

On paper: keep the network up, the servers running, the staff supported across macOS, Windows and mobile. In practice, being a company's only IT person for fifteen years is a different discipline from working in a team. There is no escalation path — you are the escalation path. Every decision has to be made knowing you'll personally live with its maintenance burden for a decade, which turns out to be an excellent filter against fashionable complexity.

That constraint shaped everything on this page, and it's the through-line to the CaseConduit build: architecture chosen so one person can operate it isn't a compromise — done properly, it's a forcing function for simplicity.

02The long migration: metal to managed

I inherited a classic 2000s estate — onsite servers, local file shares, on-premise email — and over the years retired all of it, deliberately and without drama.

The judgement call
Migrations at a 25-person company have a property big-company case studies never mention: there is no maintenance window that doesn't hit someone's deadline, and no second administrator to roll things back while you sleep. The discipline is sequencing — service by service, each step reversible, each cutover boring. Fifteen years of that is where my instinct for incremental, always-live change comes from.

03Security as a habit, not a project

04Running IT as a business function

Sole-charge IT is half engineering, half stewardship of other people's money and time.

05What fifteen years proves

ContinuityOne administrator, fifteen years, no gap in cover — institutional knowledge that never walked out the door

Longevity in a sole-charge role is itself the reference: a business doesn't keep its only IT person for fifteen years unless things work, costs make sense, and the person is someone non-technical colleagues can actually talk to.
