API integrations and business system connections

I connect applications to services, registries, payments, and hardware. I handle data exchange between existing systems and interfaces for new business applications.

What I can deliver

APIs and data exchange

REST/SOAP, XML/JSON, imports, and exports. We clarify the data source, structure, and update rules.

Payments, finance, and registries

Experience with Worldline, Kontomatik, NRKI/BRKI, ARES, and RÚIAN. The scope depends on the available interface and access.

Devices and connected systems

Payment terminals, LED panels, and other external devices. I assess connections against the documentation and operational requirements.

The design also covers service outages, retries, and tracing errors. We agree on verification based on the available test environment and API provider capabilities.

How we start

Tell me which systems need connecting, which data must move, and whether you have API documentation. We first review interface capabilities and required access.

We agree on scope and an estimate. I verify changes as I work and check important updates in a test environment before deployment.

Let's discuss your project

Tell me what works today, what you need to change, and what outcome you expect. I will get back to you with a suggested next step.
