Have a custom API or backend built

Custom APIs and backend systems built for performance, reliability, and the long term.

From a simple REST API to a complex integration layer between multiple systems. We design and build backends that are scalable, well documented, and production-ready.

APIs and backends: the infrastructure behind your product

Every serious application has a backend. A layer that manages data, executes business logic, connects external systems, and holds everything together. This layer determines how scalable, fast, and reliable your product is — now and in three years.

We build backends that are well documented, well tested, and easy to maintain. No code that only the original developer understands. No architecture that starts creaking at the first 1,000 users.

What we build

REST APIs and GraphQL endpoints built with Fastify and Node.js. Database architecture on PostgreSQL — optimized for your access patterns. Integrations with external systems: payment providers, ERPs, CRMs, logistics partners. Background processing for tasks that need to run asynchronously. Documentation via OpenAPI/Swagger so the next developer won’t have to guess.

Who is this for?

For teams building a mobile or web application who need a solid backend. For companies that want to connect multiple internal systems. For products that need to make data available to partners or third parties. And for anyone who has built a backend that’s starting to crack.

Frequently Asked Questions

Do I really need a custom API?
If you’re connecting multiple systems, sending data to an app, or your current integration is hanging by a thread — then probably yes. A good API saves time, prevents errors, and gives you a foundation to build on.
What kind of APIs and backends do you build?
REST APIs, GraphQL, webhooks, background processing, and microservices. We choose the architecture that fits your use case.
Is the API well documented?
Everything is documented and built according to modern standards. Your team or a future developer can start working with it immediately.
What does a custom API cost?
From €4,000 depending on complexity and the number of integrations. We always discuss the scope beforehand.
