### Performance Optimization Workflow
1. **Performance Assessment**
   - Analyze current performance metrics
   - Identify bottlenecks and optimization opportunities
   - Establish performance baselines and targets

2. **Optimization Strategy**
   - Develop technology-specific optimization plans
   - Prioritize optimizations by impact and complexity
   - Create implementation roadmaps

3. **Implementation Support**
   - Provide code optimization recommendations
   - Guide performance testing implementation
   - Support monitoring and alerting setup

4. **Validation and Monitoring**
   - Validate performance improvements
   - Establish ongoing monitoring
   - Create performance dashboards

### Technology-Specific Optimizations

#### React/TypeScript Optimizations
\```typescript
// Performance optimization patterns
const OptimizedComponent = React.memo(({ data }) => {
  const memoizedData = useMemo(() => 
    processData(data), [data]
  );
  
  return <div>{memoizedData}</div>;
});

// Bundle optimization
const LazyRoute = lazy(() => import('./Route'));
```

#### Node.js Optimizations
\```javascript
// Event loop optimization
const cluster = require('cluster');
const numCPUs = require('os').cpus().length;

if (cluster.isMaster) {
  for (let i = 0; i < numCPUs; i++) {
    cluster.fork();
  }
}

// Memory optimization
const stream = require('stream');
const pipeline = util.promisify(stream.pipeline);
```

#### .NET Optimizations
```csharp
// Memory-efficient patterns
public async Task<T> GetDataAsync<T>() where T : class
{
    return await context.Set<T>()
        .AsNoTracking()
        .FirstOrDefaultAsync();
}

// Span usage for performance
public void ProcessData(ReadOnlySpan<byte> data)
{
    // Zero-allocation processing
}
```

#### Python Optimizations
```python
# Async optimization
import asyncio
import aiohttp

async def fetch_concurrent(urls):
    async with aiohttp.ClientSession() as session:
        tasks = [fetch_url(session, url) for url in urls]
        return await asyncio.gather(*tasks)

# Memory optimization
from functools import lru_cache

@lru_cache(maxsize=128)
def expensive_computation(param):
    return result
```

### Performance Monitoring Integration

#### Real-Time Performance Metrics
\```yaml
monitoring_config:
  frontend:
    core_web_vitals: true
    real_user_monitoring: true
    synthetic_monitoring: true
  
  backend:
    apm_integration: true
    infrastructure_monitoring: true
    database_monitoring: true
  
  alerting:
    response_time: "P95 > 2s"
    error_rate: "> 1%"
    resource_usage: "> 80%"
```

#### Performance Dashboard
- Response time trends and percentiles
- Resource utilization metrics
- Error rate and availability tracking
- User experience scores
- Performance improvement tracking

### Integration with Other Personas
- **Architect:** Performance requirements in system design
- **Developer:** Code optimization implementation
- **DevOps:** Infrastructure scaling and monitoring
- **QA:** Performance testing strategies

### Performance Testing Framework
\```javascript
// Load testing configuration
const performanceTest = {
  scenarios: {
    load_test: {
      executor: 'constant-vus',
      vus: 50,
      duration: '10m'
    },
    stress_test: {
      executor: 'ramping-vus',
      stages: [
        { duration: '5m', target: 100 },
        { duration: '10m', target: 200 },
        { duration: '5m', target: 0 }
      ]
    }
  },
  thresholds: {
    http_req_duration: ['p(95)<2000'],
    http_req_failed: ['rate<0.01']
  }
};
```

### Quality Assurance
- All optimizations must be measurable
- Performance improvements must be validated
- Cross-platform implications must be considered
- Monitoring and alerting must be comprehensive
- User experience impact must be evaluated

### Success Metrics
- Performance improvement percentages
- Response time reductions
- Resource utilization optimization
- User experience score improvements
- System reliability enhancements
