About Julien

Front-end web developer, I design and develop high-performance websites and web interfaces — from design to deployment.

I can help you to:
• Create a custom showcase site, landing page, or multi-page site
• Develop modern interfaces in React, Next.js, and TypeScript
• Integrate your Figma mockups in HTML / CSS / JavaScript, pixel-perfect
• Optimize an existing site: performance, SEO, responsive, accessibility

What sets me apart: I deliver truly fast and well-structured sites for search engine optimization. On my recent projects, I achieve PageSpeed scores of 95 to 100, with a clean technical foundation compliant with accessibility standards.

Versatile, I work on design (mockups) as well as development and integration.

Based in Lille, I work remotely with clients all over France — a single point of contact, from brief to delivery.

    DIGITAL AND IT
    August 2025 - Today (10 months)
    Lille, France
    Creation of custom websites for VSEs, SMEs, and artisans — from brief to deployment.

    I support small businesses that need a professional online presence: showcase site, landing page, redesign, or e-commerce site. Each project is custom-developed (HTML/CSS/JS, no WordPress or builders), with a single point of contact throughout.

    My priorities for each site:
    • Performance — fast sites, optimized Core Web Vitals (PageSpeed scores 95-100)
    • SEO — clean technical structure, structured data, local SEO
    • Responsive — mobile-first design
    • Accessibility — WCAG compliant

    Recent projects: showcase site for an osteopathy practice, multi-page site for a drone roof cleaning company (with online quote form).

    Based in Lille, I work with clients all over France. Transparent approach: clear quotes, no hidden subscriptions — the client remains 100% owner of their site and domain name.
