& Technical SEO

React · Next.js·TypeScript·Core Web Vitals·Lighthouse 100
Your site is losing traffic because it's slow and invisible in search. I fix performance bottlenecks, close technical SEO gaps, and set up proper analytics — so your traffic grows and converts instead of bouncing. Backend, UI/UX, and integrations covered when needed — no handoffs, complete solutions.

01/ what_i_do
// 01
Performance Optimization
Audit and rebuild React/Next.js for Core Web Vitals. Lazy loading, code splitting, SSR/SSG — whatever it takes to hit Lighthouse 100 in production.
// 02
Technical SEO
Semantic structure, meta setup, Search Console integration, crawlability fixes. Sites that rank — not just sites that load fast in isolation.
// 03
React / Next.js Development
Scalable component architecture, TypeScript, REST API integrations, real-time dashboards. Clean code built for production, not screenshots.
// 04
Analytics & Integrations
GA4, GTM, Search Console, social pixels. Traffic that becomes real actionable data — not numbers in a report nobody reads.
