N+1 query problems occur when loading related models without eager loading. Use Eloquent's `with()` method to eager load relationships in a single query, specifying columns selectively to reduce data transfer and improve API response times.

Build RESTful APIs using Laravel's resource controllers with clean separation of concerns. Combine controllers handling HTTP logic, DTOs for request/response shaping, and service layers encapsulating business logic to ensure maintainable, testable code.

Efficient Eloquent queries use eager loading, select specific columns instead of `select('*')`, leverage `firstOrCreate()` and upserts for atomic operations, and wrap related operations in transactions to prevent race conditions and maintain data integrity.

Yes. Artisan commands automate common backend operations like migrations, seeding, and custom tasks. Combine them with service layers and validation to build robust automation that enforces business logic and maintains code quality.

Laravel's request validation framework enforces rules before data reaches your service layer. Validate input early, use custom rules for complex logic, and shape responses with DTOs to maintain clean API boundaries and prevent invalid data propagation.
