About Sylvain

Freelance web developer, I design modern, fast, and secure websites, focused on visibility, performance, and ease of maintenance.

I specialize in creating custom static websites with modern technologies like Astro and Next.js. This approach results in very fast, better-ranked, more secure, and more resource-efficient sites than traditional ones.

When the project requires it, I connect the site to a headless CMS, most often WordPress in headless mode, to allow the client to easily manage their content without sacrificing performance.

What I concretely offer

Creation of showcase and institutional websites
Overhaul of existing sites with performance improvements
Setup of blogs via headless CMS
Cookie-free or GDPR-compliant websites
Modern UX and conversion-oriented design
Optimized and secure hosting
Maintenance, domain name, and professional email included depending on the service

My approach

I favor simple, robust, and durable solutions. Each project is designed to be fast to load, easy to maintain, and scalable over time.
I work autonomously, rigorously, and transparently, with clear guidance at each stage of the project.
My goal is to deliver a reliable and efficient website, not a complex system.
