Core Web Vitals & Optimization

Engineered for Extreme Speed

In the modern web, every 100ms delay costs 7% in conversions. I build lightweight, search-optimized applications that guarantee a sub-second load time and score green in Google Lighthouse audits.

Vendor Comparison

Why Clients Choose Ayush Kumar

Hiring a developer shouldn't feel like a gamble. Here is how my performance, delivery speed, and technical standards compare to traditional agencies and low-cost outsourcing.

Traditional Agency

$$$$ (Overpriced)

High overhead, slow execution, layers of project managers.

  • ✕
    Slow Load Times

    Often 3s–6s loading times due to bloated WordPress themes.

  • ✕
    Indirect Communication

    You talk to Account Managers, not the developer writing your code.

  • ✕
    Bloated Timelines

    Layers of bureaucracy delay launches to 2–3 months.

  • ✕
    No Performance Guarantees

    No penalty clauses or refund policies if your site scores red.

    Inconsistent responsiveness, timezone delays, or ghosting.

Optimization Framework & Stack

High scores are not accidental. They are the product of combining modern structural patterns with rigorous asset delivery controls.

Next.js App Router (React Server Components)

Minimizes the client-side javascript bundle size by rendering structures on the edge.

Asset Compressing Pipelines

Images converted to modern WebP/AVIF formats dynamically, and 3D models compressed using Draco mesh pipelines to reduce asset payloads by up to 90%.

Edge CDN Delivery & Staging

Static pages are fully prerendered and cached closer to your global clients via Vercel Edge networks to reduce TTFB (Time to First Byte) under 40ms.

Semantic SEO & Core Web Vitals Scoping

Pre-connecting third-party font resources, avoiding layout shifts (CLS) through fixed layout skeletons, and preserving valid HTML5 heading hierarchies.
