I work on designing and building SAP systems on SAP BTP, with a focus on cloud-based application architecture and long-term maintainability. My work emphasizes clear service boundaries, well-defined authorization, and explicit responsibility placement so systems remain understandable and stable as they evolve. My focus areas include: Application and service architecture on SAP BTP Secure, maintainable SAP extensions and integrations Authorization design, enforcement, and responsibility boundaries Process automation and optimization using SAP-native capabilities Modern Fiori-based user experiences aligned with backend design I also share practical observations on modern SAP development and system design.
