Halden Systems

Quiet infrastructure for small teams

We are a two-person consultancy. We build and run Linux hosts, build pipelines and storage for research groups and product teams that would rather not run infrastructure themselves.

Most engagements start with a two-week audit and end with a handover document your own engineers can follow.

What we do

Host operations

Provisioning, hardening, patching and on-call runbooks for small fleets of Linux servers.

Build systems

Reproducible builds, artefact storage and release pipelines that survive a laptop replacement.

Storage

Backup design, retention policy and restore drills. A backup you have never restored is a guess.

Documentation

Written runbooks and architecture notes, delivered as part of the work rather than as an extra.

How we work

Fixed scope, fixed price, no long-term contracts. We work in the open: every change lands in your repository, every decision is recorded, and you own the hosts and the accounts from the first day.

Availability

We currently schedule new work from the following quarter onwards. Write to hello@example.com with a short description of the system and the problem.
