I have a production Next.js site that already looks and functions well, yet still feels sluggish in places and under-delivers on SEO metrics. I’ve gathered a clear, itemised list of problem areas—slow initial paint on key pages, Core Web Vitals warnings, and inconsistent behaviour on smaller screens—and I’m ready to hand that list over the moment we start. Your main brief is performance optimisation, with three targets in mind: • Lightning-fast page-load speed • Noticeable gains in SEO performance (especially Core Web Vitals) • Rock-solid mobile responsiveness The codebase is React 18 / Next.js 13. You’ll have access to the repo, build pipeline, and my Lighthouse/GTM data. If you prefer TypeScript, you’ll fit right in; the project already uses it for most components. I’m particularly interested in how you leverage AI coding assistants or performance-profiling tools to accelerate the work, so please mention those in your reply. Alongside that, include: • A couple of portfolio links, focusing on React/Next.js builds • A short note on a recent SEO or performance win you engineered • Your hourly rate and estimated weekly availability Once we agree on scope, I’ll share the full issue list plus acceptance criteria. Let’s get this site racing.
