Performance work often lands in the backlog after launch, when traffic is already leaking. By then, fixes are expensive because they touch entrenched patterns—unoptimized images, blocking scripts, and layouts that shift as fonts load.
Measure what users feel
Lighthouse scores help, but field data tells the truth. Track LCP, INP, and CLS on real devices and networks. Pair metrics with session replays to see where hesitation happens.
Ship less, load smarter
Split routes, defer non-critical scripts, and serve images in modern formats. Many wins are incremental—each one compounds into a product that feels instant and credible.
