Frontend: React, TypeScript, Vite, Zustand, React Query, Glassmorphism UI
Backend: Node.js, Express, Prisma (SQLite)
AI: Google Gemini 3 API (Gemini 2.5 for fallback)

The system follows a modern client-server architecture powered by Generative AI:

graph TD
    User[User] -->|Interacts| Client[React Client]
    Client -->|API Requests| Server[Node/Express Server]
    
    subgraph Backend
    Server -->|Auth & Data| DB[(SQLite Database)]
    Server -->|Context Construction| PromptEngine[Prompt Engine]
    end
    
    subgraph AI Cloud
    PromptEngine -->|Structured Prompt| Gemini[Google Gemini 3 Flash]
    Gemini -->|JSON Timeline Data| PromptEngine
    end
    
    PromptEngine -->|Parsed Response| Server
    Server -->|Real-time Updates| Client

Usaid leverages the advanced reasoning capabilities of Google Gemini 3 to simulate complex human life paths.

We don't just ask "what happens next?". We build a rich context object for every request:

• User Profile: Risk tolerance, core values, life priorities.
• Current State: Age, career, location, relationship status.
• Decision Matrix: The specific choice being weighed (e.g., "Quit job to start a startup").

Gemini is instructed to generate 3 distinct timeline archetypes concurrently:

• The Optimistic Path: High risk, high reward.
• The Pragmatic Path: Balanced, steady growth.
• The Pessimistic/Safe Path: Low risk, potential stagnation.

We utilize Gemini's JSON mode to ensure determinstic, parsable data for our frontend. Every event in the timeline includes:

• year: Time offset
• event: Description of the event
• impact_score: -10 to +10 quantification of impact
• category: Financial, Emotional, Career, or Relationship

Corporate strategists use "Scenario Planning" to make billion-dollar decisions. Usaid brings this military-grade cognitive tool to personal life choices.

By making the abstract future concrete and visible, Usaid reduces anxiety and helping users make faster, more confident life pivots.
