Administered network infrastructure for over 1,000 servers, ensuring optimal system deployment, security, and troubleshooting.

Situation. The company’s operations sat on top of a big server estate — over a thousand of them — and an estate that size doesn’t stay reliable on its own. Deployment, security and the steady stream of things that go wrong all need someone running them with actual discipline, or the whole thing gets flaky and nobody’s quite sure why.

Task. Administering that network infrastructure was the job — keeping it secure, keeping it reliable, keeping it consistent at a scale where inconsistency is what kills you.

Action. The network infrastructure ran across more than a thousand servers. How systems got deployed was standardised, so a server came up the same predictable way instead of each one being a little bit bespoke; the security was hardened rather than trusting that nobody would come looking; and the troubleshooting got handled when something did break. At that scale the standardisation is what saves you — a thousand snowflakes is unmanageable, a thousand of the same thing is just work.

Result. The estate ran with reliable deployment, solid security and problems that got dealt with promptly instead of festering. That’s the kind of infrastructure work that’s invisible when it’s going well, which is the point — it was the stable backbone everything else at the company ran on.
