I audit your site with Lighthouse, fix what's dragging the mobile score down, and give you the before/after numbers. Target: +20 points or 90+ on mobile. If a third-party script or platform limit blocks a fix, I'll flag it in writing before I start. You get the updated code or settings, and a short report listing every change. Example: I built a SaaS marketing page that scores 95+ on Lighthouse mobile with 100 on accessibility. One revision, funded through Contra, released on your approval.
