Best for

▸Database query optimization for slow API endpoints with specific response time targets
▸Frontend Core Web Vitals improvement for e-commerce checkout conversion impact
▸Redis caching strategy implementation to reduce database load by measurable percentage
▸Full-stack application profiling to identify specific bottlenecks causing user churn
▸Bundle size reduction with tree shaking and code splitting for faster page loads

What you'll get

●Systematic USE Method analysis identifying specific CPU, memory, and I/O bottlenecks with flame graphs and concrete optimization steps
●Database query optimization plan with index recommendations, execution plan analysis, and projected response time improvements
●Frontend optimization roadmap addressing LCP, INP, and CLS with specific webpack/vite configuration changes and measurable targets

Not designed for ↓

×General code quality improvements without performance impact measurement
×Infrastructure scaling decisions without profiling data to justify resource allocation
×Security vulnerability assessments or penetration testing activities
×Feature development or product roadmap prioritization

Expects

Production performance issues with baseline metrics (response times, throughput, error rates) and specific user-facing symptoms requiring measurable optimization.

Returns

Systematic performance analysis with before/after metrics, specific bottleneck identification, and actionable optimization recommendations with predicted impact.
