Why a founder-developer

You talk to the developer, not a salesperson.

On a Paris agency project, your brief passes through 3 or 4 hands before it reaches the code. Salesperson, project manager, designer, junior developer. Each step adds time, cost, and lost information.

Here, you talk directly to the person writing the code. Feedback gets implemented in hours, not days. And every line delivered reflects what we decided together, not what a manager translated for a subcontractor.

How do you set project prices?+

Websites range from €450 for a simple marketing site to €25,000+ for an e-commerce or SaaS platform. Mobile apps run €5,000 to €50,000+ depending on complexity. Monthly SEO + GEO retainers run €800 to €1,500 per month, or quote on request for custom engagements. I give you an exact quote after our discovery call.

Can I pay in installments?+

Yes. The standard breakdown is 30 % on order, 40 % at midpoint, 30 % on delivery. On larger projects or longer engagements, I'm flexible on the schedule.

Do you build WordPress sites or custom only?+

Custom only. Every site I deliver is coded in React and Next.js, with full source code on your Git repository. No paid theme, no annual plugin renewal. If you want WordPress, I can point you to someone, but I don't deliver it.

Do you do SEO alone, or only with development?+

Both. Every site I build includes solid SEO and GEO foundations. And I also offer ongoing SEO + GEO partnership starting at €800/month, with no development project required. Technical audits, content strategy, Google + AI visibility monitoring.

What if I already have tools in place (CRM, payments, email)?+

I integrate with what you already use. CRMs (HubSpot, Pipedrive, Salesforce), payment gateways (Stripe, PayPal), email tools (Mailchimp, Brevo), or in-house APIs. If an integration is missing, I build it.

Can you rebuild my existing site?+

Yes, in most cases. Sometimes a progressive rebuild makes sense (keep the URL, keep the SEO equity, redo the inside). Sometimes starting fresh is faster and cheaper. We decide together after the discovery call.

What exactly is GEO?+

GEO (Generative Engine Optimization) is the set of techniques that get your site cited in ChatGPT, Perplexity, and Google AI Overviews responses. When someone asks an AI “which web developer should I pick in Paris”, GEO makes sure your site is among the sources cited. It complements classic SEO, and in 2026, one doesn't go without the other anymore.
