Kaliop: your API and Node.js backend architect
API-First
Designing REST and GraphQL APIs
We work with your IT teams to build the back-end architectures for your digital products, backend-for-frontend web and mobile solutions using REST or GraphQL, as well as business-specific APIs and highly scalable microservices using TypeScript and Fastify.
Nest.js back-end framework
Designing SaaS and application software
We design your business applications, SaaS products and back-office systems using the best frameworks and software design principles tailored to your specific needs, ranging from classic MVC with Fastify to hexagonal/DDD architectures with Nest.js.
Cloud-First
Harnessing the power of the cloud and automation
We harness the potential of your cloud providers to automate deployments and maximise the use of managed services for NoSQL and SQL storage, queuing, automation, scalability, Function as a Service, edge runtime and caching systems.
The cornerstones of our Node.js expertise
- Nest.js expertise
We have many years of experience with back-end frameworks and precision engineering concepts such as ORMs, dependency injection, unit testing and the highly rigorous framework of Nest.js.
- Backend-for-frontend and Apollo GraphQL
We systematically implement a GraphQL backend-for-frontend 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.
See our composable commerce expertise - Fastify, edge and microservices
We maximise the cloud and edge capabilities of ‘Function as a Service’ for micro-tasks requiring high horizontal scalability and minimal response times, such as real-time computing, personalisation and fast cache rendering.
- Agentic AI and automation
We leverage AI and the best automation tools to migrate your back-ends to Node.js, develop data synchronisation between APIs, generate unit tests, migrate to TypeScript and carry out version upgrades.

[‘’]
Node.js has become an essential tool in back-end development, whether for simple REST and GraphQL APIs or complex business applications and SaaS products requiring high scalability and the use of managed cloud services. Node.js strikes an excellent balance between performance and development quality, thanks to TypeScript and highly mature frameworks such as Nest.js.
Pierre Cavalet, Technical Expert
We appreciate Nest.js’s modularity and rigorous structure, which strike a good balance between scalability requirements and code that remains testable and maintainable over time.
