⚙️ How I work

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