About Jeancy

Web design is no longer an aesthetic option: it's a legal and sustainable growth lever. 🚀

Passionate about design and web performance for over 4 years, I transform your strategic intentions into conversion interfaces.

My role? To design fast, compliant, and scalable tools that reflect your identity.

🌍 The Challenge: Reconciling Accessibility & Performance
With the European Accessibility Act (EAA), aesthetics are no longer enough. Through AIO Digital Studio and many other projects, I've developed a unique hybrid approach: I don't just design, I build scalable systems that I integrate myself with pixel-perfect fidelity.

💡 What I bring to your projects:
UI/UX & Augmented AI: I use Prompt Engineering (Midjourney, Firefly) as a productivity booster to reduce ideation cycles, explore bold concepts, and produce unique assets without sacrificing ergonomics.

Web Architecture & Technical Mastery: A specialist in the WordPress ecosystem (Gutenberg, ACF), I remain agnostic in my tool choices. I select the most suitable technology to ensure fluid, lightweight interfaces optimized for SEO.

Compliance & Inclusion: I natively integrate WCAG 3.0 standards to secure your business against legal risks and open your services to a universal audience.

Redesign or creation ex-nihilo: I transform your business objectives into high-performance digital experiences.
