## 🚀 **Enterprise-Grade Food Truck Discovery Platform**

A modern, full-stack web application built with **professional-grade architecture** and **enterprise development standards**. Features an AI-powered data pipeline, comprehensive admin dashboard, and real-time food truck discovery capabilities.

**Built with Zero Trust Development Protocol** - Every code change verified through systematic quality gates to ensure production stability.

## Key Technologies

- **Framework**: Next.js (React)
- **Styling**: Tailwind CSS
- **State Management**: Zustand, React Hooks
- **Backend & Database**: Next.js API Routes, Supabase (PostgreSQL, Auth, Storage, Edge Functions)
- **Web Scraping**: Firecrawl
- **AI-Powered Search**: Tavily AI
- **AI/ML**: Google Gemini API (`@google/genai`)
- **Mapping**: Leaflet, React-Leaflet
- **UI Components**: Radix UI, Shadcn UI
- **Testing**: Playwright (E2E), Jest (Unit/Integration)
- **Type Safety**: TypeScript

## Features

- **Food Truck Discovery**: Easily find food trucks based on location, cuisine type, and operating status.
- **Detailed Information**: View comprehensive details for each food truck, including menus, operating hours, contact information, and social media links.
- **Real-time Updates**: Get live updates on food truck locations and availability.
- **Advanced Search & Filtering**: Robust search capabilities with filters for cuisine type, price range, and operating status.

- **Data Quality Metrics**: Built-in functions and dashboards to monitor and ensure data quality.
- **Comprehensive Security**: Implemented security hardening measures across the application and database.
- **Admin Dashboard**: A secure and comprehensive interface for administrators, currently under active development. It includes:
  - **Food Truck Management**: CRUD operations for food truck data.
  - **User Management**: Oversee and manage user accounts.
  - **Data Pipeline Monitoring**: Track scraping jobs, data quality, and automated cleanup processes.
  - **System Metrics & Alerts**: Real-time monitoring of application performance and system health, with configurable alerts.
  - **Analytics**: Insights into application usage and food truck popularity.
  - **Test Pipeline**: Tools for testing data scraping and processing pipelines.

## AI-Powered Data Pipeline

The backbone of the Food Truck Finder is its intelligent, automated data pipeline. This system is responsible for discovering, processing, and storing food truck data from various online sources.

### Key Components:

- **Tavily AI for Intelligent Discovery**: The pipeline uses Tavily's AI-powered search API to intelligently discover new food trucks and their websites. This allows for a more efficient and targeted approach to data acquisition compared to traditional web scraping.
- **Firecrawl for Web Scraping**: Once a potential food truck website is identified, Firecrawl is used to reliably scrape the necessary data, such as menus, operating hours, and contact information. Firecrawl's robust infrastructure ensures a high success rate and handles the complexities of web scraping.
- **Gemini AI for Data Extraction**: The scraped data is then processed by Google's Gemini AI, which extracts and structures the information into a consistent format.
- **Supabase for Data Storage**: The cleaned and structured data is stored in a Supabase PostgreSQL database, providing a reliable and scalable data storage solution.
