Signature Design Concept

The homepage of "Let's Travel" will feature an interactive 3D globe that users can rotate and zoom into. Each continent will have clickable hotspots representing popular travel destinations. When a user clicks on a hotspot, a modal will appear with detailed information about the destination, including suggested itineraries, hotel options, and budget tips. This globe will be built using @react-three/fiber for 3D rendering and gsap for smooth animations and transitions. The interactive globe will provide an engaging and immersive experience, encouraging users to explore and plan their travels creatively.

Interaction Model & Motion Direction

The landing page will adopt a "parallax" interaction model, creating a sense of depth as users scroll through the content. Layers of atmospheric elements, such as clouds and travel icons, will move at different speeds to enhance the storytelling aspect. Internal pages, such as the dashboard and settings, will maintain a "static" interaction model to prioritize clarity and ease of use.

Non-Functional Requirements

• The application must support high availability and handle concurrent user sessions efficiently.
• The system should ensure data security and user privacy, complying with relevant regulations.
• The application must be responsive and accessible across various devices and screen sizes.

Tech Stack

• Frontend: React for Web
• Backend: Python with FastAPI
• Database: MySQL or MariaDB, using Alembic for migrations
• AI Models: GPT 5.4 for user-friendly responses
• AI Tools: Litellm for LLM Routing
• Local Orchestration: Docker, docker-compose
• Server-side Orchestration: Kubernetes

Assumptions and Constraints

• The application will primarily target users in India, considering local preferences and currency (INR).
• The chat assistant will not facilitate user-to-user interactions but will focus on user support.
• The payment flow will be a mock simulation and not handle real transactions.
