I've created a comprehensive mobile-first Parts Matcher app with the following key features:

Core Features:

• Parts Search & Discovery: Browse available parts with detailed information
• Match System: Request matches between buyers and suppliers
• WhatsApp Integration: Simulated WhatsApp notifications for match status
• Post Parts: Allow suppliers to list new or second-hand parts

Mobile-First Design:

• Responsive layout optimized for mobile devices
• Touch-friendly interface with appropriate button sizes
• Sticky header for easy navigation
• Scrollable content areas for long lists
• Mobile-optimized tabs and sheets

Key Components:

1. Search Tab: Find parts with filters for condition, price, and location
2. Matches Tab: View active matches with status tracking
3. Post Part Tab: Form for suppliers to list parts
4. Real-time Notifications: Badge indicators for new matches
5. WhatsApp Integration: Quick access to WhatsApp communication

Features Included:

• Part condition tracking (Brand New/Second Hand)
• Location-based matching
• Price comparison
• Supplier profiles
• Match status tracking (Available, Matched, Pending, Confirmed)
• Photo upload capability
• Filter and search functionality

The app uses a clean, modern design with shadcn/ui components and is fully responsive across all mobile devices. The WhatsApp integration is represented through UI elements and can be connected to actual WhatsApp Business API for real notifications.
