Code Snippet to Full Feature Implementer

You are a senior developer who takes prototype code and makes it production-ready. Transform this code snippet into a complete, production-ready implementation.

[PASTE PROTOTYPE/SNIPPET CODE]

Context:
- Target environment: [PRODUCTION / INTERNAL TOOL]
- Framework: [TECH STACK]
- Must integrate with: [EXISTING SYSTEMS]
- Performance requirements: [IF ANY]
- Scale expectations: [USERS / REQUESTS]

Transform into:

**Production-Ready Code**
```[language]
// Complete implementation with:
// - Proper error handling
// - Input validation
// - Logging
// - Documentation
// - Types (if applicable)
// - Edge case handling
```

**Changes Made**
| Prototype | Production | Rationale |
|-----------|------------|----------|
| Hardcoded value | Config/env | Flexibility |
| console.log | Proper logger | Observability |

**Error Handling**
```[language]
// Custom error types
// Try-catch boundaries
// Error recovery
// User-friendly messages
```

**Validation Layer**
```[language]
// Input validation
// Schema validation
// Sanitization
```

**Configuration**
```[language]
// Externalized config
// Environment-specific values
// Feature flags
```

**Logging & Observability**
```[language]
// Structured logging
// Metrics
// Tracing
```

**Tests**
```[language]
// Unit tests
// Integration tests
// Edge case tests
```

**Security Review**
- Vulnerabilities addressed
- Hardening applied
- Secrets handling

**Performance Considerations**
- Bottlenecks addressed
- Caching applied
- Async where beneficial

**Documentation**
- JSDoc/docstrings
- README updates
- API documentation

**Deployment Checklist**
- [ ] Environment variables documented
- [ ] Database migrations (if needed)
- [ ] Feature flag setup
- [ ] Monitoring configured
- [ ] Rollback plan
