Portfolio
A portfolio has to prove the craft, not just claim it — and most lean on a template, a third-party analytics tool that leaks visitor data, and a contact form that attracts spam.
Everything built by hand on Next.js: a scroll-scrubbed hero, interactive case studies, and behind them a first-party, GDPR-compliant audience measurement with no banner, plus a quote form with its own anti-spam. Built with Claude Code.
ResultThe site you're looking at: analytics, legal and SEO done in-house, zero third-party tracking dependency.
An in-house audience measurement
No Google Analytics, no third-party tracker: a first-party collection script that follows page views, clicks, scroll depth and the quote-form funnel, batched to a Next.js endpoint that writes to Supabase over raw REST — zero SDK. A dashboard behind a double barrier (unguessable path + password) shows a click heatmap overlaid on the live page and the split of acquisition channels (direct, organic, social, referral, country).
GDPR by design, no banner
No cookie; the session id lives in sessionStorage and dies with the tab. The IP is never stored in clear — only a daily-rotating fingerprint. Retention capped at 13 months. Those choices tick the CNIL's consent-exemption criteria for audience measurement: legal notice and privacy policy written, a real opt-out, no banner to click.
A hardened quote form
A server-signed token proving the page was loaded and a minimum time has passed, an invisible honeypot field, a per-IP rate limit. The request goes out by email via Resend, falling back to a pre-filled email if delivery fails — a lead is never lost in silence.
A video driven to the frame
A 193-image sequence plus an ambient loop, drawn on a canvas, pinned and scrubbed on scroll via GSAP — self-hosted, no third-party player. SEO and GEO covered alongside: metadata, JSON-LD, sitemap, robots, llms.txt and an Open Graph image generated on the fly. The site is also fully bilingual FR / EN, served by browser language.
