Description

⚡ Lead Front-End (Next.js/React, TypeScript) — Vercel & Cloudflare · Prototype 48 h · Core Web Vitals/INP

I design & code ultra-fast, conversion-oriented interfaces (FR/EN · Remote). I lead & deliver end-to-end web applications (scoping → UI/UX → dev → integrations → deployment).

Mobile app option : PWA or React Native/Expo (design → build → stores)

🎯 What I bring

• Next.js/React/TS (RSC, Server Actions), pragmatic UI/UX design

• Web Perf : fast rendering, click responsiveness, stable page (TTFB/LCP/CLS/INP)

• Headless Shopify E-commerce : Storefront API (GraphQL), PLP/PDP/checkout (Hydrogen/Oxygen if relevant)

• Edge deploy : Vercel / Cloudflare to reduce latency and costs

📦 Clear deliverables

• Next.js Prototype (48–72 h) + 10 min Loom video + prioritized backlog

• Mini-perf audit (before/after measurements: PageSpeed/WebPageTest)

• Production deployment (Vercel/Cloudflare) + 14-day monitoring (perf & UX)

📌 Recent examples

• Marketplace : UX/UI redesign + perf → +32% conversion (2 months), CLS −38%

• E-commerce : perf sprint (edge) → TTFB < 200 ms, LCP < 2.5 s mobile, +12% add-to-cart

• SaaS : 5-day prototype → 20 S1 tests, time-to-value −35%

• Mobile (React Native/Expo) — dating app : smooth onboarding, swipe & matching, real-time chat, notifications
