Find what'sreally slow— then fix it.
We read the waterfall, profile the call stack and pinpoint the three changes that will move your Lighthouse score from the 40s into the 90s — with evidence, not guesswork.
From 38 to 94 in one sprint
Render-blocking scripts, uncompressed images, no preloading — every resource loaded in a deep sequential chain.
Parallel critical path, font preloading, deferred third-party scripts, image CDN with responsive sizes — the network waterfall went from 8 levels to 3.
Four categories,
one report
Render-blocking scripts
3 parser-blocking JS bundles deferred — 640 ms eliminated from critical path.
Unoptimised images
WebP conversion + lazy-load on 14 images dropped page weight by 1.8 MB.
Waterfall depth
Font preload hints + resource hints collapsed a 7-level chain to 3.
Unused JavaScript
Tree-shaking + code-splitting removed 420 KB of shipped but never-executed code.
Your waterfall is telling
you something.
We read it fluently. A one-day audit becomes a ranked fix list with estimated impact — handed to your team or executed by ours.
