🏗️ 6-Layer Architecture

The platform is built on a scalable, modular architecture designed for high performance and intelligent personalization.

1. Search Orchestrator: The brain of the system; handles fan-out, deduplication, and aggregation.
2. Integration Layer: Unified adapter pattern for third-party hotel providers (Hotelbeds, Booking.com, etc.).
3. AI Matching Service: Personalization engine with Neural Ranking and reaction analysis.
4. Pricing & Availability: Real-time validation with intelligent caching (Redis).
5. User & Session: Secure authentication (NextAuth) and preference persistence.
6. Real-time Gateway: WebSocket-based live updates and AI chatbot interaction.
