Independent infrastructure, product, and operational engineering
This is circumspace
Experienced, independent infrastructure and product engineering. Honest advice, reliable systems, no vendor agenda.
What we do
Infrastructure you own
We build and run infrastructure on hardware and terms you control. Containers, virtual machines, automation, and Linux operations without lock-in or a sales agenda.
Know where it breaks
We review infrastructure, deployments, and day-to-day operations. You get an honest view of the risks, bottlenecks, and the work worth doing next.
Stop doing it by hand
We remove recurring operational work and connect the systems that do not quite fit together. Less copy-paste, fewer fragile runbooks, and more time for useful work.
When it is already broken
For incidents, failed migrations, and systems nobody wants to touch. We help establish what happened, recover safely, and leave things in a better state.
Selected experience
Interim technical leadership
Provided interim engineering management and CTO support for a German AI startup.

Freedom & permissionless Technology
We champion privacy-respecting approaches to solving problems using free software whenever possible. Our commitment to libre software principles, data minimization, and user autonomy drives every technology decision we make. We support open source initiatives for broader adoption and fundamentally believe in software freedom and user rights. If you have to ask for permission, it's not yours to begin with.
circumspace Labs
circumspace labs is our umbrella for experiments where we rapidly explore new technologies using AI assisted engineering practices.
