Product engineering studio — Abidjan · Paris
Your product at the centre, our six disciplines around it.
Yourproduct
We design, build and ship web and mobile applications — from scoping to production, security and operations included.
What we believe
A product is either operable, or endured.
A product's business logic should carry names, parameters and descriptions — not live inside its interface components. That is what makes a product operable by a command palette, by an internal API, and by an agent. This site is built that way.
What we do
See allBuild a product end to end, or advise on what already exists.
Build
The six lifecycle phases. We take the product from idea to production, then keep it running.
Advise
On a product that already exists. We deliver an audit and a migration plan, not an application.
What we have built
See allProducts, prototypes and research, with where each one stands.

Actions exposed over MCP
Publish the site's Actions layer as an MCP server, so an external agent can use it — without opening more than it should.

Assisted writing pipeline
Write an article in French, derive the English version and the metadata from it, without a model publishing anything on its own.

What we teach
See allStep-by-step guides drawn from real projects.
- A dark theme that does not flash
The theme has to be applied before the first paint, which a deferred module cannot do.

- Test the built site, not the dev server
What gets deployed and what runs in development are not the same artefact.

What we think
See allNotes and positions, not press releases.
- A React context does not cross an island boundary
The trap is expensive because it is invisible: while only one island exists, everything works.

- SMS is not a second factor
A phone number can be hijacked at the carrier, and that hijack leaves no trace on the victim's side.
Sécurité1 min read
- Selling what we practise
The studio's site is built with the architecture it sells. That is a constraint, not a turn of phrase.
