SAP BTP Security & Identity Architect building federated SSO, hybrid authorisation, and agentic AI systems on SAP BTP.

At Confidential Client (NDA), I'm developing an agentic AI system on SAP BTP to re-implement custom business logic as an LLM-driven multi-agent system. I use SAP AI Core, Python and LangChain for orchestration, with OpenSearch retrieval and containerised services on SAP BTP Kyma.

At PowerCo (VW Group) via T-Systems, I designed and led delivery of a CoPilot CPI Error Analysis pipeline that connects Gemini with SAP Cloud Integration and enriches SAP Cloud ALM alerts. I also owned BTP Core & Security for the CoPilot landscape, including federated SSO, user provisioning, role collections and principal propagation.

Through my work with clients including Fressnapf Group, Dürr Group and NetGo, I've delivered SAP BTP integrations, launchpads and hybrid authorisation concepts. At Heralding Systems GmbH, I maintain an SAP BTP sandbox for IAS, IPS and Work Zone R&D, alongside AI/ML research and reference implementations for ABAP Cloud / RAP and CAP.
