I ran WordPress for 15 years before I coded it.

Fifteen years creating pages, managing content and debugging plugins on the editorial side — then eight years building. I know exactly what to keep from your admin, and what deserves to be rebuilt behind it.

User-side expertise: 15 years running WordPress on the editorial side — I know what must be preserved in your admin.
Technical mastery: Modernised WordPress sites and bespoke web & mobile apps when WordPress is no longer the right tool.

FAQ

The questions I'm asked most

How much does a site with Next Impact cost?

Three packages: from €2,250 for an optimized WordPress, around €4,000 for Headless WordPress + Next.js, and on quote for a business application. Budget and timeline are fixed from the start.

Do I have to rebuild my whole WordPress site?

No. I keep the WordPress interface you already know to manage your content and modernize the rest — the front-end, performance, design. Your existing content is preserved.

What is Headless, in plain terms?

Your WordPress stays the back-office where you publish; a Next.js front-end displays it separately. The result: a much faster, safer, better-ranked site, without changing how you work.

Is Headless always necessary?

No, and I'd rather be upfront: for a small showcase site, an optimized WordPress is often enough. Headless becomes genuinely useful when performance, editorial SEO or scale justify it — I point you to the most cost-effective path, not the most sophisticated one.

How long until my site is delivered?

Around 2 to 4 weeks for an optimized WordPress, and 6 to 10 weeks for a Headless + Next.js architecture or a custom web app, depending on complexity.

Will I be able to manage the site myself?

Yes. You keep publishing in WordPress as before, with no technical skills. Tailored training and documentation are included.

Do you work remotely?

Yes, fully remote, across France and beyond. We work over video calls, and you keep a single point of contact from quote to delivery.
