# Women's Safety App Backend - Microservices Architecture
This project is a microservices-based backend for a women's safety application designed to handle millions of users.
## Architecture Overview
- **User Service**: Profile management, authentication
- **Emergency Service**: SOS alerts, emergency notifications
- **Location Service**: Geolocation, radius-based user discovery
- **Calendar Service**: Women's health calendar
- **Notification Service**: Push notifications
- **Gateway Service**: API Gateway and load balancing
## Technology Stack
- Python 3.11+ with FastAPI
- PostgreSQL with partitioning
- Redis for caching and sessions
- Celery for background tasks
- Kafka for event streaming
- Docker & Kubernetes
- Prometheus & Grafana for monitoring
## Development Guidelines
- Follow microservices patterns
- Use async/await for I/O operations
- Implement proper error handling and logging
- Use database migrations with Alembic
- Write comprehensive tests
- Follow security best practices

```
## WebSocket Events (Future Enhancement)
Real-time notifications for emergency alerts:
```javascript
// Connect to WebSocket
const ws = new WebSocket('ws://localhost:8000/ws/alerts');
// Listen for emergency alerts
ws.onmessage = function(event) {
const alert = JSON.parse(event.data);
// Handle emergency alert
};
```
## SDK Examples
### JavaScript/TypeScript
```javascript
class WomenSafetyAPI {
constructor(baseUrl, token) {
this.baseUrl = baseUrl;
this.token = token;
}
async createAlert(alertData) {
const response = await fetch(`${this.baseUrl}/api/v1/alert`, {
method: 'POST',
headers: {
'Content-Type': 'application/json',
'Authorization': `Bearer ${this.token}`
},
body: JSON.stringify(alertData)
});
return response.json();
}
}
```
### Python
```python
import httpx
class WomenSafetyAPI:
def __init__(self, base_url: str, token: str):
self.base_url = base_url
self.headers = {"Authorization": f"Bearer {token}"}
async def create_alert(self, alert_data: dict):
async with httpx.AsyncClient() as client:
response = await client.post(
f"{self.base_url}/api/v1/alert",
json=alert_data,
headers=self.headers
)
return response.json()

## Deployment Strategy
### Containerization (Docker)
- Multi-stage builds for optimization
- Distroless base images for security
- Health check definitions
- Resource limits and requests
### Orchestration (Kubernetes)
- Deployment manifests with rolling updates
- Service mesh for inter-service communication
- Persistent volumes for database storage
- Horizontal Pod Autoscaler (HPA)
### CI/CD Pipeline
- Automated testing (unit, integration, e2e)
- Security scanning
- Performance testing
- Blue-green deployments
- Automated rollbacks
## Data Flow Examples
### Emergency Alert Flow
1. User creates emergency alert (Emergency Service)
2. Location Service finds nearby users within radius
3. Notification Service sends push notifications
4. Alert stored with notified user count
5. Real-time updates via WebSocket
6. Analytics events published to Kafka
### Location Update Flow
1. Mobile app sends location update
2. Location Service validates and stores location
3. Cache updated with new location (Redis)
4. Location history stored (partitioned table)
5. Nearby user calculations triggered
6. Privacy filters applied
## Future Enhancements
### Phase 2 Features

## 🧪 Testing
### 1. Run Tests
```bash
# Unit tests
pytest tests/ -v
# Integration tests
pytest tests/integration/ -v
# Coverage report
pytest --cov=services --cov-report=html
```
### 2. Load Testing
```bash
# Install locust
pip install locust
# Run load test
locust -f tests/load_test.py --host=http://localhost:8000
```
### 3. API Testing
```bash
# Using httpie
http POST localhost:8000/api/v1/register email=test@example.com password=test123 first_name=Test last_name=User
# Using curl
curl -X POST "http://localhost:8000/api/v1/register" \
-H "Content-Type: application/json" \
-d '{"email":"test@example.com","password":"test123","first_name":"Test","last_name":"User"}'
```
## 🔐 Security Checklist
- [ ] Change default passwords and secrets
- [ ] Enable HTTPS with valid certificates
- [ ] Configure proper CORS origins
- [ ] Set up rate limiting
- [ ] Enable database encryption
- [ ] Configure network firewalls
- [ ] Set up monitoring and alerting
- [ ] Regular security updates
- [ ] Database backups configured
- [ ] Log rotation enabled
## 📈 Scaling Guidelines
### Horizontal Scaling
- Add more replicas for each service
- Use load balancers for distribution
- Scale database with read replicas
- Implement caching strategies
### Vertical Scaling
- Increase CPU/memory for compute-intensive services
- Scale database server resources
- Optimize Redis memory allocation
### Database Scaling
- Implement read replicas
- Use connection pooling
- Consider sharding for massive scale
- Archive old data regularly
## 🚨 Emergency Procedures
### Service Recovery
1. Check service health endpoints
2. Review error logs
3. Restart failed services
4. Scale up if needed
5. Check external dependencies
### Database Issues
1. Check connection pool status
2. Monitor slow queries
3. Review disk space
4. Check replication lag
5. Backup verification
### Performance Issues
1. Check resource utilization
2. Review response times
3. Analyze database performance
4. Check cache hit rates
5. Scale affected services
