  • ✅ Converted Streamlit app to Flask REST API
  • ✅ Created /analyze endpoint for resume analysis
  • ✅ Added health check endpoint (/)
  • ✅ Implemented proper error handling and logging
  • ✅ Added CORS support for frontend integration

2. Dependencies & Configuration

  • ✅ Updated requirements.txt with Flask, Flask-CORS, Gunicorn
  • ✅ Created Procfile for deployment
  • ✅ Added runtime.txt for Python version specification
  • ✅ Created environment configuration files

3. Frontend API Integration

  • ✅ Updated API service to use deployed backend URL
  • ✅ Enhanced error handling with specific error messages
  • ✅ Added request/response interceptors for debugging
  • ✅ Configured environment variables for API URL

4. Enhanced User Experience

  • ✅ Added connection status indicator
  • ✅ Improved error messages and user feedback
  • ✅ Added loading states with toast notifications
  • ✅ Enhanced file upload validation

5. Testing & Documentation

  • ✅ Created comprehensive integration test script
  • ✅ Added deployment guide for both frontend and backend
  • ✅ Updated README files with API documentation
  • ✅ Created test scripts for API validation

🔧 Technical Implementation

Backend API Endpoints

GET  /           - Health check
POST /analyze    - Resume analysis (multipart/form-data)

Frontend Configuration
