A site designed to perform

Every site I create is built around four pillars: a polished design, impeccable performance, solid SEO, and a user experience that converts.

🎨 Custom Design

A unique design tailored to your identity, designed mobile-first for a smooth experience on all screens.

⚡ Native Performance

Performance is not an afterthought: it is integrated from the architecture. Result: green Core Web Vitals from launch.

🔍 Integrated Technical SEO

🎯 Conversion through Design

Each page is structured to guide the visitor towards action: visual hierarchy, clear calls to action, and frictionless user journeys.

The difference is visible at loading

Frequently Asked Questions

Why choose a performance consultant to create my site?
A traditional developer builds a site and then optimizes it later. My approach is the opposite: performance is integrated from the architecture and every technical decision. Result: a natively fast site, without costly optimization layers afterwards.
What technology will be used for my site?
The choice depends on your needs: WordPress for an easily manageable site, Laravel or Next.js for custom needs, Astro for an ultra-fast showcase site. I recommend the most suitable solution for your goals and budget.
How long does it take to create a site?
A showcase site takes 4 to 8 weeks from briefing to launch. A more complex corporate site may require 8 to 12 weeks. Each project follows a detailed schedule validated together from the start.
Do you offer maintenance after going live?
Yes, I offer maintenance contracts that include security updates, performance monitoring, and functional evolutions. Maintenance ensures that your site remains performant and secure over time.

Create a high-performance site from the start

The performance of a website should never be an afterthought. Too many projects follow the same pattern: first we build, then we optimize, often at great cost. My approach is the opposite: performance is a design criterion from the technical architecture. Choice of framework, rendering strategy, asset management, image optimization — every decision is made with speed as a design constraint.

The result is a natively fast site, without layers of caching or CDN to compensate for heavy code. A site that achieves green Core Web Vitals from launch, not after weeks of optimization.

Design and user experience for conversion

A fast site with poor design does not convert. A beautiful slow site does not either. Performance and design are inseparable: perceived speed is an integral part of the user experience. A site that displays instantly inspires trust and encourages visitors to stay.

Each page is designed to guide the visitor towards action: clear visual hierarchy, well-placed calls to action, optimized forms, and frictionless navigation paths. The mobile-first design ensures a consistent experience across all devices, where the majority of your audience is.

Technical SEO: being found to convert

A high-performance site has a natural advantage in SEO. Google has made Core Web Vitals an official ranking factor. But technical SEO goes far beyond speed: correct semantic markup, structured data (schema.org), logical content architecture, clean URLs, dynamic sitemap, and optimized server response time.

These technical foundations are integrated from the design stage, not added by a plugin later. The result: a site that Google can crawl and index efficiently, with the best chances of ranking for your target queries.

Sustainable technical choices

A website is an investment over several years. The technical choices made at creation determine the maintainability, scalability, and cost of evolving your site. I favor proven technologies, well-documented, and with an active community. The code is clean, commented, and structured to be easily taken over by any competent developer.

After launch, continuous performance monitoring and a maintenance contract ensure that your site remains fast, secure, and up-to-date as your business evolves.
