Recent work

Real builds, not demos. Public sites with back-offices, written from scratch and custom made.

Lieux de Retraites↗
  • Custom website
  • Prospecting
  • Emailing
  • Newsletter
  • CRM

A directory of retreat venues across France — 250+ places, searchable by region, capacity, and budget. Behind that public site sits a back-office that runs the business day to day: prospecting, outbound email, the newsletter, and a CRM. One system instead of four tools that don’t talk to each other.

Vins de Sauternes↗
  • Custom website
  • Stock
  • Orders

A wine shop in Sauternes. The public catalogue is the shop window. The back-office is where the work happens: stock, orders, shipping rates by country. Built so someone who doesn’t “do web” can manage inventory and fulfil orders without calling a developer.

How I work

I design and ship custom tools on a stack I know end to end. I don't take over existing codebases — I start from scratch, or I replace.

FAQ

How do we talk?▸

Mostly in writing. I answer by email. Few calls: one intro call and one wrap-up for a build if you want them.

How does the retainer work?▸

One client at a time. 4–6 hours a week, async. One 30-minute call a month, max. Evolutions, automations, fixes, hosting.

Do you take over my current codebase?▸

No. I start from scratch, or I replace.

Who owns the code?▸

You do. It lives on your GitHub, your Vercel, your Stripe. I’m an admin.

Can a project run longer than 6 weeks?▸

No. If I happen to run over, you pay the same price. If I’m waiting on your reviews, we finish on a retainer.

Is there a prize for finding every easter egg on the website?▸

If you got this far, you’re already the kind of person I like working with. Email me the list and get a 10% discount on your project ✌️

Tell me what you’re trying to build, in a few sentences. You’ll get a real answer back in writing, not a calendar link.
