§04 — About

A small senior practice in data and intelligent systems.

Two principal engineers, occasional collaborators we trust, and a deliberate ceiling on the number of clients we work with at any one time.

What we sign before we open an editor.

§04a — Principles
I.

Clarity before code

Every engagement starts with a one-page artefact: what we are measuring, what we are not, and the cost of being wrong.

II.

Build to be inherited

No black boxes. Tested, documented, onboarded into your team. We measure success by the day we are no longer needed.

III.

Earn every dependency

A new tool, model, or vendor is a tax on tomorrow. We add them only when the alternative is materially worse — on the record.

Who you actually meet.
