How we work on it
The habits that keep this kind of work predictable.
Deterministic tests where money moves
Payments, refunds and entitlements get exact tests before release. It is one of our written quality bars.
Observability from the start
Structured logs, metrics and alerts ship with the first endpoint, not after the first incident.
Documented so anyone can operate it
OpenAPI specs, runbooks and architecture decision records are deliverables.
Technologies we use
The tools this work is usually built with. We keep the stack small on purpose.
