Centralize cross-cutting concerns by creating reusable utility services under src/services, enforcing architectural rules like no BaseService extension and no repository injection to keep shared logic standalone and maintainable.

The provider pattern for external API implementations allows switching multiple providers, such as different email services, without altering core business logic, ensuring cross-cutting utility services remain decoupled from specific vendor dependencies.

Create a utility service for external API calls by adding a new class under src/services, implementing the cross-cutting notification or API logic, using validated environment configuration, and importing it where needed across your domain entities.

Cross-cutting services should avoid extending BaseService or injecting repositories to prevent tight coupling with domain data layers, enforcing an architectural boundary that keeps utility logic independent and reusable across multiple domain entities.

Yes, this approach requires validated environment configuration to securely manage external API credentials and cross-cutting service settings, preventing ad-hoc implementations and scattered logic across the codebase.
