Shopify App Developer - Multi-Stage Chat & Support Platform

I need an experienced Shopify app developer to build a comprehensive customer support platform with AI chat integration and live support features.

The project involves creating a Shopify app with three distinct stages:

Stage 1: AI-powered chat feature where customers can ask basic Shopify questions. The app should integrate with Google Gemini API to provide text-based answers (no video links).

Stage 2: Secure theme access feature that allows authorized developers to connect Claude AI to client sites for theme coding. This feature must be locked by default and only accessible with a special unlock code.

Stage 3: Paid credit system for live support where customers can purchase credits to chat with real support agents for website fixes and assistance.

Requirements:
• Proven experience developing Shopify apps
• Strong proficiency in Liquid templating language
• Advanced JavaScript skills
• Experience with Shopify API integrations
• Knowledge of Google Gemini API integration
• Experience with Claude AI API
• Ability to implement secure access controls and payment systems
• Understanding of credit-based payment models
• Experience with real-time chat functionality

Deliverables:
• Fully functional Shopify app with all three stages
• Clean, well-documented code
• Integration with specified AI services
• Secure authentication system for stage 2 features
• Payment and credit management system for stage 3
• User-friendly interface that integrates seamlessly with Shopify admin

This is an hourly project with potential for ongoing maintenance and feature additions. The app will serve 600+ clients, so scalability and reliability are crucial.
