01Your need

You know what you want to achieve. Now it has to ship.

Launch

You have an idea for an AI product, and it needs to reach real users.

Starting pointA prototype to try, then the build
Evolve

Your product already exists, and you want it to evolve (a new feature, a migration or AI) without weakening what works.

Starting pointUnderstanding what exists, a prototype, then the build
Stabilize

Your application is slowing down, failing under load, or costing too much on AWS.

Starting pointA measured diagnosis, then the fixes
02Fast and right

AI speeds things up. Experience decides what goes to production.

Fast

A prototype to try from the first week.

Then a first version live, at the pace your need calls for. No months of meetings before you see anything.

Nearly
20years

in production, from national media to the screens of major railway stations: AI writes fast, every line is reviewed, and anything that is not solid does not ship.

Business ideas, not just code

You get reasoned proposals, designed for your users:

The approach in detail

Review of a change: “order export”

Example · 1 day

  • Write the order export and its tests

    KeptReviewed line by line

  • Read every order in a single query

    FixedPagination: the table holds millions of rows

  • Write the access key into the code

    RejectedKey stored in a secrets vault

  • The most powerful AI model to sort incoming requests

    ReplacedA lightweight model is enough: cost per request cut by 10

  • Delete the failing test

    RejectedThe test revealed a real bug, now fixed

5 AI proposals: 1 kept as is, 4 reworked.Live the same evening, after your approval.

What the AI proposes, what experience keeps. Illustrative example.

The same standard, also applied within a medical team: Echosens
