Performance tuning

Stop losing customers to every extra second of waiting.

A slow application costs money: every extra second of load time sinks conversion and drives abandonment. Nothing here is optimized by guesswork. We instrument, measure and attack the real bottleneck — which is almost never the one the team assumes. Backend and frontend profiling, request waterfall analysis, Core Web Vitals, and API latency at the 99th percentile, not the average that hides everything.

What's included

  • 01Backend and frontend profiling with real production data, not synthetic tests
  • 02Core Web Vitals (LCP, INP, CLS) and perceived-load optimization
  • 03API latency analysis at p95/p99 and of the dependency waterfall
  • 04Edge caching, CDN and invalidation strategy
  • 05Load testing to find where your system breaks before a customer does
