I will nextjs performance and boost your lighthouse score


About this gig
Is your Next.js website slow, or losing SEO rankings due to low Core Web Vitals?
Google's search ranking depends on speed. I am a professional Next.js developer, and I will perform a deep technical audit and optimization to make your web application lightning-fast and SEO-friendly.
What I will do to your Next.js app:
- Core Web Vitals: Improvement of LCP, FID, and CLS scores.
- Rendering Strategy: Setting up SSR (Server-Side Rendering) or ISR (Incremental Static Regeneration) for optimal speed.
- Image Optimization: Implementing next/image, modern formats (WebP/AVIF), and lazy loading.
- Bundle Reduction: Code splitting, tree shaking, and removing heavy unused libraries.
- Hydration Fixes: Resolving "Hydration failed" errors and reducing Total Blocking Time (TBT).
- Caching & Edge: Configuring Middleware and headers for faster delivery.
Why speed matters:
- Lower Bounce Rate: Users leave if a site takes more than 3 seconds to load.
- Higher Conversions: Faster sites sell more products.
- SEO Boost: Google prioritizes fast, optimized websites in search results.

FAQ
Do I need to provide the source code?
Yes, I will need access to your GitHub/GitLab repository to implement the technical changes directly.
Will the optimization break my site's design?
No. I focus on technical performance (code, images, scripts) without changing your UI/UX design.
Can you guarantee a 90+ score?
In 95% of cases, yes. If your site uses heavy third-party scripts (like massive 3D models or dozens of trackers), I will optimize them as much as technically possible and provide a detailed report.
