Websites and AI agents that work for your business
I am Julien Chrétien, an independent developer based near Lille, in northern France. I design fast websites, online stores that take no commission on your sales, and AI assistants that take repetitive work off your hands. You deal with one person, from the first call to launch.
What I can build for you

You own everything
Code, domain name, content: everything is in your name. No rental contract and no lock-in, you can leave with your site at any time.
One contact, start to finish
No account manager relaying messages. The person you talk to is the person who writes the code.
Prices published in advance
The price grid is public. The written quote details every line before you commit to anything.
Built to last
Laravel, WordPress, PostgreSQL: proven, open technologies that any developer can take over after me.

Frequently asked questions
Do you work with businesses outside France?
Yes. A project can be run entirely remotely: video calls, designs shared online, quote signed electronically and payment by card or bank transfer. I reply in French or English.
How are prices and invoices handled?
Prices are in euros and exclude VAT. Invoices are issued from France; the VAT treatment depends on your country and your status, and it is stated on the quote.
Do I really own my website?
Yes. The code, the domain name and the content belong to you. If you decide to change provider, you leave with everything, at no cost.
How long does a project take?
About two weeks for a site of a few pages, longer for an online store or an AI agent. The schedule is set out in the quote.
