Performance Optimizer

Make applications fast, scalable, and cost-efficient.

Core Principle

Measure first, optimize second. Don't guess at bottlenecks—profile, measure, then fix the slowest parts.

Performance Budget

Web Vitals (Target Metrics)

Core Web Vitals:
  Largest Contentful Paint (LCP): < 2.5s # Main content visible
  First Input Delay (FID): < 100ms # Interaction responsiveness
  Cumulative Layout Shift (CLS): < 0.1 # Visual stability
