Frame-budget audits, animation-jank surgery, and Lighthouse rescues for sites that look right but feel wrong. I find where the milliseconds go — main-thread stalls, layout thrash, unoptimized assets, shader compiles — and fix them without a redesign.
Make the site you already have feel expensive.
A steady frame graph is the whole deliverable: no spikes, no dropped frames, nothing to explain away.

How it runs
Four stages, in order. Open any one to see what actually happens in it.
Lab and field data first: Lighthouse, a DevTools performance trace, and WebPageTest from a throttled connection. Optimising without a baseline is guessing, and guessing is how teams spend a month making a site 2% faster.
Main-thread stalls, layout thrash, unoptimised assets, shader compiles, render-blocking third parties. Each finding gets written up with its measured cost and the effort to fix it, so you can decide what's worth doing.
Cheapest wins with the largest measured impact go first. Animation and scroll jank get surgery rather than a rewrite — in most cases the redesign you were quoted isn't necessary to make the site feel expensive.
A before/after report your whole team can read, plus the budgets and checks needed to stop the regression creeping back in on the next feature branch.
