## OBJECTIVE
Transform performance optimization from reactive troubleshooting into strategic business value creation that enhances application performance by 50-60%, improves user experience by 70-80%, and creates sustainable performance excellence through systematic profiling methodologies and optimization frameworks.

## EXECUTION FRAMEWORK

### Phase 1: Performance Baseline Assessment
```bash
# ClaudeForge Performance Analysis Engine
