Infrastructure done right.

We're a collective of software engineers obsessed with getting infrastructure right. That means systems that are secure by design, reproducible from first principles, and built to perform under pressure. We believe the best software is boring in the best way — predictable, auditable, and quietly reliable.

What we stand for

Infrastructure that is predictable, auditable, and quietly reliable.

Secure by Design

Security is an architectural concern, not an afterthought. We build systems with minimal attack surface, zero-trust networking, and least-privilege access from the ground up.

Reproducible from First Principles

Every environment is defined in code. No snowflakes, no configuration drift, no surprises. We use NixOS and Nix flakes so any system can be rebuilt exactly as intended.

Built to Perform Under Pressure

We build systems that stay reliable when it counts most. Observability is wired in from day one — Prometheus, Grafana, and alerting before anything goes to production.

Predictable

Declarative configuration means the system does exactly what the code says. No hidden state, no manual steps, no tribal knowledge required.

Auditable

Everything is in version control. Every change has a diff, a review, and a history. You always know what's running and why.

Quietly Reliable

The best infrastructure is the kind you never have to think about. We aim for boring systems — stable, well-understood, and out of the way.
