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 three years from now.
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 to creak with 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 doesn't have to guess.
Who is this for?
For teams building a mobile app or web application who need a solid backend. For companies wanting to connect multiple internal systems. For products that need to make data available to partners or third parties. And for anyone whose backend is starting to crack.
Custom API development, database architecture, third-party integrations, background processing, microservices.
When do you need custom API development?
- You are building an app and need a backend. From authentication to data storage — everything behind the user interface.
- Your systems don’t communicate with each other. Your CRM doesn’t know what your webshop knows. Your backend doesn’t know what your ERP knows. We connect them.
- Your current backend doesn’t scale. Slow queries, timeouts, architecture problems — we honestly assess what needs to be done.
- You want to make data available to partners. A documented API that others can safely use.
Utrecht doesn’t have Amsterdam’s ego or Rotterdam’s edge. It has its own vibe — and it works. The city is scaling fast. Your digital presence should too.
