I will improve core web vitals and speed up your website
Vahid
About this gig
Is a slow website costing you visitors, leads, and sales? I will diagnose the real performance bottlenecks and improve Core Web Vitals, PageSpeed, and Lighthouse results without hiding problems behind a report. I optimize LCP, CLS, INP, caching, assets, images, JavaScript, CSS, database queries, and backend response time where your package allows. I have 7+ years of engineering experience and have improved a production Lighthouse score from about 25 to 90+ and reduced backend response time from roughly 10 seconds to 400 ms. You receive tested changes, before-and-after evidence, and a clear explanation of what was fixed. Send me your URL before ordering and I will confirm the best package. Final scores depend on hosting and third-party scripts, so I promise honest engineeringnot fake guarantees.
