Enterprise-grade websites and platforms.

The website is your most visible digital asset. It must rank on Google, convert visitors, and hold up over years. We engineer custom websites and scalable platforms on Next.js, optimized for technical SEO, mobile experience, Core Web Vitals score and raw speed. No technical debt, documented code, Vercel hosting included.

Three pillars of a high-performance website

Measured technical performance

Lighthouse 95+, Core Web Vitals in the green, LCP under 1.5s, CLS near zero. Optimized Next.js 16 code, AVIF/WebP images, self-hosted fonts, global Vercel edge caching.

Production-grade technical SEO

Clean URL architecture, semantic HTML5, Schema.org structured data, auto-generated XML sitemap, robots.txt, hreflang FR-EN, canonicals, dynamic meta per page, Open Graph, Twitter Cards. Indexable, crawlable, rankable.

Conversion measured by default

GA4 or Plausible installed, conversion events configured, anti-spam forms, A/B testing pre-wired, CRM integration or Slack/Email notifications. You measure what works from day one.

Typical use cases

WordPress to Next.js migration

Slow, insecure, hard-to-edit WordPress site. Full migration to Next.js with SEO preservation: 301 redirects, slug retention, Search Console audit, gradual authority restoration. Typical gain: 3x LCP, 2x conversions.

B2B brochure site engineered for acquisition

B2B SMB needing qualified leads. Service pages optimized per query, pillar + cluster content, embedded quote forms, UTM tracking, automated lead nurturing. Local SEO for service businesses ranking on the target geography.

Scalable editorial platform

Multilingual international site

Frequently asked questions

+How long does it take to ship a website?

Custom B2B site: 4 to 8 weeks. Editorial platform or multilingual site: 8 to 16 weeks. Schedule validated at project start, weekly deliveries on Vercel preview.

+Will you redo my WordPress site?

WordPress remains relevant for some uses, but most of our redesigns migrate to Next.js for performance, security, technical SEO and absence of fragile plugins. Migration preserves existing SEO via 301 redirects and canonical URL retention.

+Will the site be optimized for Google?

Yes, technical SEO is integrated from design: URL architecture, Schema.org structured data, XML sitemap, hreflang, dynamic meta, Core Web Vitals in the green. Content SEO (semantic audit, editorial plan, copywriting) is a complementary service.

+Who hosts and maintains the site?

Hosting on Vercel (global edge network), included for the first year. Maintenance on monthly subscription (updates, monitoring, support). You retain 100% ownership of the source code, delivered to your GitHub repository.
