Željko Popov — SAP BTP & Enterprise Integration Architecture Catalog

SAP Integration Suite Architecture Governance Engineering Rigor

Welcome to my Open-Source SAP Enterprise Integration Reference Library. This catalog contains 30 production-grade architectural blueprints built on SAP Business Technology Platform (SAP BTP) and SAP Integration Suite, complete with exported BPMN2 (.iflw) packages, Spock Framework TDD unit test suites (with mocked com.sap.gateway.ip.core.customdev.util.Message contracts), SAP Project Piper GitOps pipelines, and Architectural Decision Records (ADRs).
