I develop secure custom APIs and connect websites, bots, applications, payment systems, databases, and third-party services. I can build REST APIs, webhook systems, authentication, customer synchronization, order processing, payment notifications, background tasks, data imports, reporting endpoints, and administrative integrations.
This service is ideal when two systems need to exchange information or when your application needs a reliable backend. I can review API documentation, design the integration, implement secure credentials, handle errors, prevent duplicate requests, log activity, and create testing tools. I can also repair incomplete or unreliable integrations that are failing to synchronize data correctly.
