   ```
   POSTGRES_PASSWORD=<generate-random-string>
   REDIS_URL=redis://localhost:6379/0
   JWT_SECRET=<generate-with-python-secrets>
   ENVIRONMENT=production
   LOG_LEVEL=INFO
   ```
5. Wait for sync & auto-deploy (~5-10 minutes)
6. Test: `curl https://yourusername-data-cleaning-openenv.hf.space/api/health`

### Step 3: Deploy Frontend to Vercel (⏱️ 10 minutes)
1. Go to https://vercel.com/dashboard
2. Import repository: `AnubhavKiroula/data-cleaning-openenv`
3. Set root directory: `frontend/`
4. Add environment variable:
   ```
   VITE_API_BASE_URL=https://yourusername-data-cleaning-openenv.hf.space/api
   ```
5. Deploy
6. Test: Open https://data-cleaning-openenv.vercel.app

### Step 4: Smoke Test (⏱️ 10 minutes)
1. Upload sample CSV from frontend
2. Start cleaning job
3. Monitor job progress
4. Download cleaned results
5. Verify data quality

**Total Time to Production**: ~40-50 minutes

## 🚀 Production Deployment Targets

### Backend: HuggingFace Spaces
- **Why**: Free tier, no credit card required, Docker support, GitHub sync
- **Resources**: 16GB storage, shared compute (cold starts OK)
- **Cost**: Free
- **Deployment**: ~10 minutes

### Frontend: Vercel
- **Why**: Free tier, GitHub integration, global CDN, fast deployment
- **Resources**: Unlimited bandwidth, serverless functions
- **Cost**: Free
- **Deployment**: <5 minutes

### Database: SQLite (on HF Space) or PostgreSQL (external)
- **Option 1 (Recommended)**: SQLite with HF Space storage
  - Pros: No external DB, simpler setup, free
  - Cons: Limited to single-instance
- **Option 2**: PostgreSQL on external service
  - Pros: Better for scaling
  - Cons: Additional cost (~$15/month)

## ⚠️ Known Limitations & Future Improvements

### Current Limitations
1. **Multi-tenant auth**: JWT implemented, but not fully tested in production
2. **Real-time updates**: Using polling instead of WebSockets
3. **Advanced monitoring**: Basic monitoring in place, comprehensive stack not deployed
4. **Scaling**: Single-instance setup; would need load balancer for HA

### Future Improvements
1. Add nginx reverse proxy for routing
2. Enable auto-scaling for Celery workers
3. Set up log aggregation (ELK stack)
4. Add custom domain with SSL
5. Implement rate limiting for API
6. Add API key authentication
7. Set up comprehensive monitoring with alerts

---

## 🆘 Troubleshooting

### If backend won't start on HF Spaces
- Check HF Space logs for errors
- Verify environment variables are set correctly
- Ensure POSTGRES_PASSWORD is strong and set
- Check that the image is accessible in GHCR

### If frontend can't connect to backend
- Verify VITE_API_BASE_URL is correct
- Check browser console for CORS errors
- Ensure backend is running and responding to requests
- Verify health endpoint: `curl <backend-url>/api/health`

### If Docker images aren't building
- Check GitHub Actions logs
- Verify Dockerfile syntax
- Check for missing dependencies
- Review docker build output for errors
