Declaration Delivery Notification Service
Component Detail
Description
Sends push notifications or in-app notifications to drivers when a confidentiality declaration is ready for acknowledgement. Tracks delivery status and triggers coordinator alerts if a declaration remains unacknowledged after a configurable period.

Summaries
This service ensures drivers are promptly informed when confidentiality declarations require their attention, directly reducing compliance gaps that could expose the organization to legal liability. By automating reminder escalations and coordinator alerts, it eliminates manual follow-up overhead, accelerates declaration turnaround, and creates a reliable audit trail demonstrating due diligence in managing sensitive assignment disclosures. The result is lower operational cost, reduced compliance risk, and a professional driver experience that supports workforce retention.
Medium-complexity backend service requiring integration with a push notification provider and configurable reminder scheduling. Key delivery dependencies include the notification infrastructure choice (FCM, APNs, or in-app WebSocket), the declaration lifecycle state machine, and the coordinator alert routing logic. Testing must cover delivery failure handling, reminder cancellation race conditions, and configurable delay parameters. Deployment requires environment-specific notification credentials and a scheduler (cron or queue-based).
Estimate 4–6 days including integration tests and failure-path coverage.
Backend service exposing four core interfaces: sendDeclarationDeliveryNotification, scheduleAcknowledgementReminder, notifyCoordinatorOfAcknowledgement, and cancelPendingReminders. The reminder scheduler must be idempotent to avoid duplicate notifications on retry; use a persistent job queue (e.g., Bull, pg-boss) rather than in-memory timers. Delivery failure handling should implement exponential backoff and dead-letter logging. The service has no declared dependencies but will in practice consume a notification gateway and declaration state repository.
Cancellation on acknowledgement must reliably dequeue pending reminders to prevent ghost alerts after the driver has already acted.
Responsibilities
- Send initial delivery notification to driver
- Schedule follow-up reminder if unacknowledged
- Notify coordinator when driver acknowledges
- Handle notification delivery failures gracefully
