FRONTEND // ASTRO & REACT

Frontend ThatLoads FastAnd Converts.

Astro SSR for marketing sites. React for dashboards and interactive tools. Vite for SPA and micro-frontend architecture. Lighthouse 95+ by default.

// FRONTEND_STACK

Three Frontend Modes

< ASTRO SSR />

Marketing sites, landing pages, blog + KB systems. HTML ships to the browser. React islands only where needed. Sub-second LCP. Lighthouse 95–100.

< REACT APPS />

Client portals, admin dashboards, complex forms, calculator tools. React 18 with server components where applicable. Tailwind + shadcn/ui.

< VITE MICRO-APPS />

Embeddable widgets, calculator iframes, and SPAs that need fast HMR and tree-shaken bundles under 50kb.

What I Build for Clients

🚀

Marketing Sites (Astro)

Agency sites, SaaS landing pages, and portfolio sites. SSR with CMS-driven content. Conversion-optimized layout. Lighthouse 100.

📊

Dashboards (React)

Analytics dashboards, client portals, and internal tools. Real-time data via WebSocket. Recharts for visualization.

🧮

Calculator Tools (React/Vite)

ROAS, CAC, LTV, ROI calculators. Embeddable on any site. API-backed for logged calculations. Lead capture built in.

📰

Headless CMS Frontends

Astro or React consuming WordPress REST API, Sanity, or a custom PostgreSQL CMS. Content editable without code changes.

🎨

Design System Implementation

Tailwind-based component libraries. Consistent tokens, dark mode, and component documentation.

⚡

Performance Optimization

Core Web Vitals audit and fix. LCP, CLS, INP. Image optimization, font loading, JS reduction. Lighthouse 40 → 95+.

Why Astro Over Next.js for Marketing

Next.js is a great framework for app development. For marketing sites it ships too much JavaScript. A page that should be 40kb of HTML ends up being 300kb of JS because of the Next.js runtime.

Astro solves this with the island architecture: HTML by default, JavaScript only where the component needs it. A Astro marketing site with a React contact form will ship zero JavaScript to pages that do not need the form.

The result: LCP under 1 second, Lighthouse scores in the 95–100 range, and a Core Web Vitals pass without heroic optimization effort. For a client site where every second of load time costs conversions, this matters.

When I use React instead: dashboards, interactive calculators, real-time data apps, anything with complex client state. React 18 + server components for the best of both worlds.

// COMMON_FRONTEND_PROBLEMS

What Is Broken in Most Agency Sites

After auditing dozens of marketing sites the problems follow a pattern. Performance is always the first casualty.

  • ⚠ 400kb+ JavaScript bundle on a page with no interactivity
  • ⚠ No image optimization — 4MB hero images blocking LCP
  • ⚠ Google Fonts blocking render — 600ms font download before first paint
  • ⚠ No OG tags, no schema markup, no canonical URLs
AUDIT [WARN] LCP: 4.8s (threshold: 2.5s) — Hero image unoptimized
AUDIT [WARN] JS bundle: 412kb gzipped — 90% unused on initial load
AUDIT [FAIL] No schema markup. Missing LocalBusiness JSON-LD.
FIX [OK] After Astro rebuild: LCP 0.9s, JS 12kb, Lighthouse 98.
_ AFTER_REBUILD: LIGHTHOUSE_98
