} satisfies Engineer;- Boring tech first β I won't introduce a framework that costs more than the problem it solves.
- Real dependencies in tests β Testcontainers over mocks, every time.
- Idempotency from day one β money endpoints and event consumers ship with keys.
- Compile-time over runtime β strict TypeScript, discriminated unions, branded types.
- One log per state transition β structured events; metrics for counts; traces for latency.
