The first week
Every engagement opens with a short scoping exchange and a written one-page scope document. The scope names the outcome, the deliverables, the timeline, the decision-maker, and what we need from you. You sign it before any work starts. We sign it before any invoice goes out.
Repo access, environment credentials, and a shared channel — usually Slack or your team's equivalent — are set up on day one. By the end of week one, the schema, product thesis, or equivalent foundational decision is on the table, in writing, with the tradeoffs clear enough to debate.
