Steps for completing your project
After purchasing the project, send requirements so K M can start the project.
Delivery time starts when K M receives requirements from you.
K M works on your project following the steps below.
Revisions may occur after the delivery date.
Phase 1: Deep Audit & Diagnosis
Start as a Google Lighthouse speed optimization expert Next.js by performing a Google PageSpeed CWV audit. Pinpoint root causes of slow loading, like bundle bloat and inefficient rendering, using technical analysis tools.
Phase 2: Execution & Fixes
As a Next.js speed optimization specialist and Core Web Vitals expert, I fix LCP/TTFB via caching/SSR and optimize INP with code splitting. I ensure zero CLS and proper script loading, transforming the app into a high-performance site.
