About Johan

Web Developer | Next.js | React | Headless CMS

Is your website slow, difficult to edit, or not converting? I design custom showcase and e-commerce websites with Next.js + headless CMS (Sanity, Payload, Shopify).

Result: a site that loads in under a second, can be edited independently, and is SEO optimized.

My latest projects: Lighthouse 95+, loading 0.6 to 0.9s, 100% responsive.

① Premium Showcase Site — Next.js + Sanity
Fast, elegant, animated site (GSAP / Framer Motion). You manage your content yourself via Sanity Studio. Ideal for SMEs, restaurants, agencies, artisans, firms, consultants. Delivered with training to be autonomous from day 1.

② E-commerce Store — Shopify Headless + Next.js
All the power of Shopify (products, payments, logistics) with a custom, ultra-fast, and SEO-friendly front-end. No more limitations of classic themes.

③ Performance Redesign — WordPress/Webflow → Next.js
Does your site take 4s to load? I'll migrate it to Next.js + headless CMS. Loading time divided by 4, better SEO, modern experience.

Why me?
→ Next.js + headless specialist — it's my core business, not just another skill.
→ GSAP / Framer Motion animations — sites that don't look like templates.
→ 15 years of professional experience before development (quality analysis, media sector). Result: rigor, deadlines met, understanding of your business needs.
→ Clean, documented code, no technical debt.

Stack: Next.js, React, TypeScript, Tailwind, Sanity, Payload, Shopify Headless, Node.js, PostgreSQL, Stripe, Vercel.
