FlutterFlow Snack Discovery App

I'm looking to build an app that helps users discover Indian ready-made snacks using an OpenAI-powered chatbot.

Key Requirements:
- Built in FlutterFlow
- Firebase backend (Auth optional, Firestore, Hosting)
- Chatbot powered by OpenAI (gpt-o4 mini)
- Amazon PA API integration (with my affiliate tag)

The chatbot will search snacks based on:
- Mood (e.g., happy, sad)
- Region (e.g., North, South)
- Health (e.g., low calorie, high protein)

Snack results will include:
- Snack images
- Short descriptions
- Affiliate "Buy Now" links

I’ll provide all snack categories and filters.

Ideal skills and experience:
- Proficiency in FlutterFlow and Firebase
- Experience integrating OpenAI and Amazon PA API
- Strong UI/UX design skills

Please share your portfolio, previous projects, estimated timeline, and cost.
