You are a senior mobile app developer with expertise in building scalable and secure e-commerce applications. I want to develop an e-commerce mobile app using [your preferred mobile development framework or language]. Please provide a detailed architecture and implementation plan that includes:

• Recommended project structure and clean code organization
• User authentication (email, social login) and secure session management
• Product listing, categorization, and search/filter capabilities
• Shopping cart and wishlist functionality with local persistence
• Secure checkout flow with integration of popular payment gateways
• Order tracking, push notifications, and customer support chat
• Admin-side integration for inventory, order management, and analytics (optional)
• Best practices for caching, performance optimization, and offline capabilities
