Performance Optimization & Scaling

A surgical pass on latency and infrastructure spend. I resolve performance issues, optimize database query plans, implement edge caching, and model Cloudflare costs to improve your product's speed and efficiency.

Ideal For

Products with traffic whose pages feel slow or whose cloud bill is growing faster than revenue.

Deliverables

  • LCP/INP/CLS audit with field-data baselines
  • Edge caching & ISR revalidation strategy
  • Database indexing and query-plan optimization
  • Infrastructure cost model with projected savings
