API & Integration

API & Integration

REST APIs and third-party integrations.

Most business systems need to talk to something else — a payment gateway, an IoT device, another team's backend. We design REST APIs and integration layers that are documented, versioned, and built to be a stable contract other systems can depend on.

This is the connective layer behind most of our other services: the ERP systems, automation pipelines, and cloud deployments we build all communicate through APIs designed this way.

What This Covers

  • REST API design and development
  • Third-party service integration
  • IoT device and sensor integration
  • Authentication and access-control layers
