Designs NestJS feature modules with clean dependency boundaries, provider scopes, and dynamic modules. Use when adding a new feature module, splitting a monolithic AppModule, or fixing tangled imports between modules.

Builds thin NestJS controllers that parse input, invoke a single use case, and map the Result to ApiResponse<T>. Use when adding HTTP endpoints, refactoring fat controllers, or applying API versioning.

Prepares a NestJS service for production: graceful shutdown, health/readiness, structured logs, config, Dockerfile, CI gates, and rollout safety. Use when promoting a service to staging/production or auditing readiness.

Designs NestJS application services as use-case classes that orchestrate domain logic and ports without leaking the framework. Use when creating new use cases, refactoring services that mix HTTP/DB/domain, or moving from anemic services to OOP.

Maps internal AppError hierarchy to HTTP responses through a single global exception filter and a Result-to-HttpException helper. Use when adding new error types, fixing inconsistent error responses, or removing scattered try/catch in controllers.

Implements the Repository pattern with TypeORM in NestJS so domain entities stay framework-free, ORM models live in infrastructure, and transactions are explicit. Use when adding persistence, refactoring leaky ORM usage, or handling transactions across…

Tests NestJS applications at unit, integration, and e2e levels using Test.createTestingModule and Supertest with hand-rolled fakes. Use when writing tests for use cases, controllers, or full HTTP flows.
