Discover our expertiseAPI Management
Designing, managing and orchestrating an API ecosystem
We help you structure your IT system and avoid the pitfalls of ‘spaghetti architecture’ or data fragmentation by establishing the right data repositories, implementing practical synchronisation mechanisms, and ensuring the long-term management of your REST and GraphQL APIs.
From monolithic to modular
Gradually modernising your IT system
We tackle ‘replatforming’ challenges deemed impossible, taking a phased approach to breaking down your monoliths – seamlessly and without holding back your ambitions – whilst making effective use of agent-based AI and ‘vibe coding’.
The cornerstones of our expertise in composable architecture
- Agent-based AI and ‘vibe coding’
We provide you with modern development accelerators to speed up the creation of front-end applications, API endpoints, admin interfaces and functional tests, as well as to test interactive prototypes.
- Back-to-front and REST / GraphQL
We systematically implement a back-to-front approach across our composable architectures to ensure strict decoupling between front-ends and SaaS or legacy back-end APIs, using Apollo, Fastify, TypeScript and a suite of unit tests.
- Front-end expertise in Vue/React
We build high-quality, high-performance Vue/React front-ends, combined with finely tuned API orchestration, to deliver a seamless end-to-end user experience.
- Expertise in React Native and Flutter
Our experience in native mobile development enables us to confidently tackle cross-platform iOS and Android apps, ensuring they integrate seamlessly with your web roadmap and make the most of your API ecosystem.
Discover our React Native expertise - Headless CMS Expertise
Our experience with headless CMS enables us to design and optimise your data models to streamline content creation, translations, asset management and workflows, tailoring them to each group of contributors.
Discover our CMS headless expertise - Headless e-commerce expertise
We develop the necessary content plugins and connectors between your headless e-commerce solution and the other APIs in your ecosystem, such as DAM, PIM, CDP, Loyalty, Search and your legacy ERP systems.

How do you transition from a monolithic architecture to a composable architecture?
Monoliths have a tendency to complicate the migration to a composable architecture. Not always knowing where to start, and sometimes fearing the ‘house of cards’ effect, decision-makers may invest indefinitely in version upgrades until the solution and the associated skills are exhausted or disappear.
The approaches typically taken as the first steps towards a composable architecture are:
- Complete decoupling of the front-end and back-end (100% API), which can sometimes be challenging when the monolithic application does not provide full API coverage. However, the investment required to develop the missing APIs is often worthwhile in the long term, as it allows you to benefit from a standalone front-end.
- The gradual decoupling of the front-end and back-end by gradually integrating the new front-end using JavaScript widgets, ESI/SSI, progressive URL routing to the new platform (reverse proxy), or user experience techniques such as full-page mode, a back button and a side panel.
- The gradual decoupling of the back-end from the front-end, by progressively replacing functions of the monolithic architecture with external tools (search, CDP, PIM, headless CMS, headless e-commerce, custom APIs, etc.).
Gilles Guirand, CTO
The choice of architecture, particularly composable architecture, has an impact on the organisational, technical and financial aspects of a digital project. New alternatives are emerging on the market, but these sometimes require a rethink of the project design, as well as the expertise and skills available within the teams.
