About this gig

Connect your applications and business systems with a reliable custom API integration.


I develop and integrate REST APIs, webhooks, OAuth flows, API-key authentication, JSON or XML data exchanges, databases, payment services, ecommerce tools, CRMs, shipping services, and custom business applications.


You receive a clearly scoped implementation designed for maintainability: data mapping, validation, error handling, logging strategy, secure credential handling, testing, and handoff notes as appropriate to the package.


I can build a new backend endpoint, connect an existing product to a third-party service, repair an incomplete integration, or design a multi-step workflow between systems. Access must use official documentation and credentials the client is authorized to provide.


Complex integrations vary significantly by API quality, rate limits, authentication, and existing code. Please message me with the API documentation, desired workflow, current stack, and expected data flow before ordering multi-system work.
