No ready-made template: we start from what you do every day, and from what wastes your time. Then I design the tool, screen by screen, before writing the first line of code.
A bar, a list, some buttons: the structure falls into place, in colour, in your words. You see it running early and often, so you can correct things while it's easy.
Client record, calendar, dashboard, quote, job tracking: each task in your day becomes a simple screen, designed for your thumb. Nothing more than you need.
Payments, calendar, emails, till, carrier: the app talks to the tools you already have. An order comes in, the team is notified, the client gets a confirmation. Nothing to type twice.
Phone, tablet, computer: the same app, the same data, instantly. iOS, Android, browser or a full platform with subscriptions: we choose what fits how you work, not the other way round.
Your data stays yours, updates are included. Just below, a real phone is waiting for you: unlock it, open the apps, turn it around.
Mobile, web, platforms, SaaS, marketplaces, business tools, automation, artificial intelligence. From the first screen to launch.

This page
This phone is a real little app, written in plain HTML.
Light or dark theme, in Settings.
Animations off if your device asks for it.
Ten kinds of apps. Tap one to see what it is and what it's for.
iOS and Android, native or progressive
An app on the App Store and Google Play, or an installable web app that behaves like a native one. Notifications, offline mode, camera, payments.
Works in any browser
A fast, logged-in space that works on a computer as well as a phone, with nothing to install. Accounts, roles, real-time data.
Subscriptions, multiple clients, billing
A product your clients use online, with subscriptions, recurring payments, multiple organisations and complete administration.
Sellers, buyers, commissions
Several sellers, buyers, split payments, reviews, moderation. All run from a simple admin.
Management, scheduling, bookings, invoicing
The tool that fits the way you work, instead of spreadsheets and generic software that waste your time.
Your repetitive tasks, done on their own
A form that creates the quote, an email that fills the spreadsheet, an order that alerts the team on Telegram. Repetitive tasks disappear.
Your services, connected to each other
Connect your site to your till, your CRM, your accounting software, a carrier, a payment method. Or open your own data to your partners.
Assistants, documents, agents
An assistant that answers your clients with your real information, a document reader that pulls out what matters, an agent that prepares the work for you.
Modernise without breaking everything
An existing app that is slow, shaky or abandoned by its developer. I take it over, secure it and modernise it, without interrupting your business.
Monitoring, updates, quick response
Once live, the app stays monitored, backed up and updated. One person to talk to, a report every month.
Real projects, for real clients.

On the studio's tablet, the client chooses placement or removal, reads, fills in and signs with a finger. The PDF goes to the client by email, and a copy reaches the studio. Fourteen days later, an email invites them to leave a Google review.
La Cour des Miracles, tattoo and piercing

The same consent app, set up for the studio: tattoo, piercing, legal texts specific to the trade, a copy for the studio. Built once, adapted in a day.
Lucyome Paris, wish candles

Screenshot of the app, translated for this page.
A single page where the client finds her whole project: the brief, what she needs to prepare, the mockups to compare, the progress. Nothing to remember, nothing to dig out of emails.
Personal project

Screenshot of the app, translated for this page.
A planning app designed for an ADHD brain, not a game. Daily, weekly and monthly tasks become short quests, with an instant reward for every ticked box: points, a level that goes up, a pot of coins that pays for something you really want. A streak of days to keep, and a “Flame of Grace” that forgives a missed day, so you don't give up at the first slip. In the evening, an end-of-day form sums it up.

Every work session becomes a floor of a Minecraft tower, with its windows lit when work is happening. A dashboard you explore like a game. Here, a demo with invented projects: the real tower stays private.

A Tokyo-style island where buildings light up according to the state of projects, tasks and AI agents. A real 3D game that runs on a phone, connected to live data.

An assistant that listens, thinks and answers out loud, without any data leaving the computer. A macOS app and web interface, with AI models running locally.

Three clear tutorials on AI agents: ideas and prices, security, private AI. To explain to a client what can be done for them, and what it costs.

Real screenshot of the app.
Type an equation, get the solution and the reason for each step, as on an exam paper. Exact solving for linear and quadratic equations, polynomials with rational roots, biquadratic equations, quotients, square roots, exponentials, logarithms, absolute values, sine, cosine and tangent, linear systems, inequalities and differential equations y′ = ay + b. Everything else is solved numerically, and it says so clearly. Each solution is plugged back into the original equation to check it.

A cat to feed, cuddle, play with and let sleep. It has a name, three outfits and an opinion about you. Everything is saved on the device, with no account and no connection.

Real screenshot of the app.
A public service of dubious interest: four situations to dodge, five degrees of utter nonsense, and a certificate of unforeseen circumstances to copy. The last three excuses stay in the archive.

Thirty seconds to tap the potatoes popping out of the vegetable patch, without touching the chillies. Two difficulty levels, streaks that score more, a record kept on the device, and a pause when you switch tabs.
Noria Torréfaction, Lyon — fictional company

Real screenshot of the app.
Noria doesn't exist: it's an invented coffee roaster, eight employees and seven business clients, made up to show an admin app without exposing a real client's numbers. The home screen says where the money is: €823.20 in late invoices, €1,267.20 in drafts never sent, €2,288.40 to collect, three leave requests to approve.

What the new La Cour des Miracles site brings the studio, in real numbers.
Requests received through the site, month by month
Before the rebuild, the site received no requests: there was no form. June covers the first three weeks after launch. July is estimated between two real readings.
Every request goes through the site's form, so every request is counted.
Your flashes, your gallery.
Forgot or lost your code? Ask the studio manager.
Replica of the real app, with the site's public flashes. Demo account: nothing is sent.
4 flashes on display
Photograph the drawing flat, in daylight. It appears on the site right after you send it.




“Booked” keeps the flash visible on the site, crossed out: it shows things are moving.
It appears at the top of your profile right after you send it. Avoid photos where the client's face can be recognised without their consent.

Photos without a cross are the ones installed when the site launched. To remove one, ask the manager.
In the real app, the idea goes to the manager on Telegram.
Real app: PHP with no database, OVH shared hosting, Telegram notifications, automatic monthly report, protection against repeated login attempts.
Three questions, and I know what we're talking about.
