The asynchronous lifecycle of Pix keys
Ownership claims, provider webhooks, and local records had to remain coherent across an asynchronous journey with multiple failure modes.
Treat consistency as an explicit lifecycle, with idempotency and reconciliation instead of relying on the illusion of one synchronous request.
Event-driven state transitions, idempotent consumers, and recovery paths aligned local and external state while keeping each step observable.
Led the backend work from architectural design and data modeling through integrations, infrastructure, rollout, and production observability.
