// Engineering — 02

Systems that hold under load.

Backend systems, integrations, deployment infrastructure, and the operational discipline around them. The practice is simple to describe: build systems that are easy to explain, hard to break, and honest when they fail.

// A — Principles

Six commitments the work is held to.

  1. 01Isolate everything

    Every system ships as its own container group with its own network, ports, and certificates. One client's deploy never becomes another client's incident.

  2. 02Boring infrastructure wins

    Proven tools, few moving parts, no cleverness where a script will do. Excitement belongs in outcomes, not in runbooks.

  3. 03Data has gravity

    Schema first. Migrations versioned. Append-only where history matters. Every backup treated as fiction until a restore proves otherwise.

  4. 04Automate the second time

    Do it manually once, deliberately. The second time it happens, it becomes a script with logs and a retry path.

  5. 05Observability over hope

    Healthchecks, structured logs, and a status surface per stack. If a system can't say how it's doing, it isn't done.

  6. 06Legible by default

    Records, audit logs, and runbooks that outlive the moment they were written for. Future-me and the client's next engineer are the audience.

// B — Architecture

The shape of the system.

// C — In practice

Where this shows up in practice.

Production systems built and operated under these rules — anonymized where agreements require it.
