OGWallet Credit Card Data System - Summary

🎉 What We Built

A complete system for crowdsourcing, processing, and displaying credit card offers and benefits data in the OGWallet app.

📦 Components Created

1. Python Data Processing Server (data-server/)

Files:

• main.py - FastAPI server with REST endpoints
• models.py - Pydantic data models for validation
• forms_processor.py - Microsoft Forms integration
• git_manager.py - Git repository management
• process_excel.py - Script to process Excel exports
• init_sample_data.py - Initialize with sample data
• test_setup.py - Quick setup script (no dependencies)
• requirements.txt - Python dependencies
• .env.example - Configuration template

Features:

• ✅ Process Microsoft Forms responses (API or Excel)
• ✅ Validate and deduplicate data
• ✅ Store data in JSON format
• ✅ Automatic git commits and pushes
• ✅ REST API for data access
• ✅ Sample data generation

2. Data Repository (ogwallet-data/)

Structure:

ogwallet-data/
├── data.json              # Complete dataset
├── offers/                # Individual offer files
│   ├── offer-001.json
│   ├── offer-002.json
│   └── offer-003.json
├── benefits/              # Individual benefit files
├── redemptions/           # Redemption options
└── README.md

Sample Data:

• 3 credit card offers (Dining, Gas, Shopping)
• 3 redemption options (Cash Back, Travel, Gift Cards)
• Ready to use immediately

3. Kotlin Integration (composeApp/)

Files:

• src/commonMain/kotlin/dev/consumerfinance/ogwallet/data/CreditCardDataLoader.kt
  • Data models for offers, benefits, redemptions
  • JSON deserialization
  • Sample data fallback

Updated:

• src/commonMain/kotlin/dev/consumerfinance/ogwallet/ui/screens/OfferRewardsScreen.kt
  • Now loads data from CreditCardDataLoader
  • Converts hex colors to Compose Colors
  • Displays crowdsourced offers

4. Documentation

Files:

• CREDIT_CARD_DATA_SETUP.md - Complete setup guide
• data-server/README.md - Server documentation
• data-server/MICROSOFT_FORMS_TEMPLATE.md - Form template
• data-server/quickstart.sh - Unix setup script
• data-server/quickstart.bat - Windows setup script

🚀 Quick Start

Option 1: Use Sample Data (Immediate)

cd data-server
python3 test_setup.py

This creates sample data in ogwallet-data/ that the app can use immediately.

Option 2: Full Setup (Production)

cd data-server
./quickstart.sh  # or quickstart.bat on Windows

Then:

1. Create Microsoft Form using the template
2. Export responses to Excel
3. Process: python process_excel.py responses.xlsx

📊 Data Flow

Users → Microsoft Forms → Excel Export → Python Server → JSON Files → Git Repo → Kotlin App → UI

🎯 Use Cases

1. Crowdsourcing Credit Card Offers

• Share Microsoft Form with community
• Users submit offers they discover
• Automatic processing and validation
• Data appears in app

2. Maintaining Up-to-Date Offers

• Regular Excel exports from Forms
• Run process_excel.py to update data
• Git tracks all changes
• App loads latest data

3. Community Contributions

• Users upvote/downvote offers
• Track offer popularity
• Filter by category, bank, card

🔧 API Endpoints

Once server is running (uvicorn main:app --reload):

• GET / - Health check
• GET /stats - Processing statistics
• POST /process-forms - Process new responses
• GET /offers?category=dining - Get offers
• GET /benefits?card_name=Chase - Get benefits

📱 App Integration

The app automatically loads data from CreditCardDataLoader:

val creditCardData = CreditCardDataLoader.loadData()
val offers = creditCardData.offers
val redemptions = creditCardData.redemptionOptions

🔄 Git Submodule Setup (Optional)

To use git submodules for automatic updates:

# In ogwallet-data directory
git init
git add .
git commit -m "Initial data"
git remote add origin https://github.com/yourusername/ogwallet-data.git
git push -u origin main

# In OGWallet directory
git submodule add https://github.com/yourusername/ogwallet-data.git composeApp/src/commonMain/resources/data

📈 Next Steps

1. Create Microsoft Form
   • Use template in MICROSOFT_FORMS_TEMPLATE.md
   • Share with community
2. Set Up Automation
   • GitHub Actions for scheduled processing
   • Automatic data updates
3. Enhance Data
   • Add more offers and benefits
   • Implement upvoting system
   • Add verification workflow
4. Improve App
   • Add filtering and search
   • Show offer popularity
   • Enable user submissions from app

🎨 Features in the App

The OfferRewardsScreen now displays:

• ✅ Credit card offers with gradients
• ✅ Category-based emojis
• ✅ Expiry dates
• ✅ Redemption options
• ✅ Upvote/downvote counts (ready for implementation)

🛠️ Technologies Used

• Backend: Python, FastAPI, Pydantic
• Data: JSON, Git, Microsoft Forms
• Frontend: Kotlin, Compose Multiplatform
• Integration: Git Submodules, REST API
