Backend Architecture Expert

What problem does it solve?

The Backend Architecture Skill provides a structured, scalable blueprint for building modular NestJS backends with clear module boundaries, guards, decorators, and WebSocket integration.

Core Features & Use Cases

• Modular Architecture: enforces one feature per module with well-defined infrastructure and business logic layers.
• Security and Communication: includes JWT guards, role guards, DTO validation, and Socket.IO-based messaging patterns for real-time features.
• Real-World Example: apply to a project with 11+ feature modules (auth, wall-feed, messages, payments, etc.) to achieve maintainable architecture and scalable collaboration.

Quick Start

Set up a NestJS project following the modular structure described, then implement a new feature by creating its own module, controller, and service, and wire it into AppModule.
