I built a RESTful payment integration connecting ServiceNow with NCR Payment Solutions / Global Pay Solutions so users could purchase items through a connected application workflow.

My contribution

Alongside the integration, I created C4 architecture documentation to explain the system context, platform containers, and REST API components. The diagrams let readers move from the overall business interaction to the technical dependencies behind it.

Engineering focus

This project combines API integration, ServiceNow development, and technical communication. Documenting the boundaries and dependencies makes the implementation easier for other developers to understand and maintain.

Technologies: ServiceNow, REST APIs, NCR Payment Solutions / Global Pay Solutions, C4 architecture documentation.
