Product engineering studio — Abidjan · Paris

We design, we build, we ship.

At the centreYour product

Build01 / 06
Discovery

Frame the product before the first line of code, so the budget builds instead of correcting.

Service details

One partner, the whole cycle: from design to deployment, a single team that thinks product and writes production code.

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.

The advisory service The research under way
Example ActionestimateQuote({modules:"discovery,design"})

A visible signature, callable by the interface and by an agent alike — the same one, never two paths.

What we do

See all

Build 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.

Agent-Native Architecture Advisory

Make an existing product agent-operable without rewriting it — and without opening more than it should.

Products, prototypes and research, with where each one stands.

ProductIn testing

Yorro.dev

The studio's own site: showcase, journal and tutorials, built as a demonstration of the architecture it sells.

  • TypeScript
  • Tailwind CSS
  • Cloudflare Pages

ResearchRoadmap

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.

  • MCP
  • TypeScript
  • Cloudflare Workers
PrototypeRoadmap

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.

  • MDX
  • TypeScript
