🏗️ Architecture

Backend (Hexagonal Architecture)

Strict separation of concerns:

✅ Domain Layer (Pure Business Logic)
  ├── Zero framework dependencies
  ├── Testable without NestJS
  └── 90%+ code coverage target

✅ Application Layer (Controllers & DTOs)
  ├── REST API endpoints
  ├── Input validation
  └── DTO mapping

✅ Infrastructure Layer (External Adapters)
  ├── TypeORM repositories
  ├── Redis cache
  ├── Carrier connectors
  ├── Email service
  └── S3 storage

Key Benefits:

• Domain can be tested in isolation
• Easy to swap databases or frameworks
• Clear separation of concerns
• Maintainable and scalable

Frontend (Next.js 14 + React 18)

Modern React stack:

• App Router with server components
• TypeScript strict mode
• Tailwind CSS + shadcn/ui
• TanStack Query for state
• react-hook-form + zod for forms
