Mathieu Ferran · Independent developer
Games, software, apps and websites.
From scoping to delivery, in batches that finish.
Games and a desktop application under the 7Sail label, mobile apps, websites. And for artists, craftspeople and entrepreneurs starting out, administrative and documentation support, remote, anywhere in France.
Who it is for
Two ways to work together.
Artists, craftspeople, entrepreneurs
Protect your name, gain visibility, equip your business.
An availability search for your name at €49, then the trade mark filing prepared with you, your name reserved everywhere, a brochure site, markets and fairs listed. The rest on a written quote, remote, anywhere in France.

Scope a project, prototype an idea, ship a first product.
Audit and reset, prototype or vertical slice, a product from scoping to delivery. Godot for games, Flutter for mobile, Tauri for desktop. Every batch has an acceptance criterion and an audit.

Offline readings, no account and no subscription. Interpretation depends on the position as much as on the card, and the journal stays on your machine, readable without the software.
The method
What does not change from one project to the next.
Scope before code
What is in the batch, what is not, and why, in a dated document that lives with the project.
Batches that finish
A start, an end, an acceptance criterion. What overflows opens a batch, what drags on gets cut.
What ships is measured
Every promise is held by a test that fails when it stops being true.
