Responsible for solution design and architecture for communication channels and system connectivity between SAP S/4HANA Cloud, SAP BTP, a custom-built buying solution, SAP Ariba, Matrix42, Salesforce, and various catalog systems. The primary objective was to ensure that each system could operate independently while enabling event-driven data exchange, centralized monitoring, scalability, and extensibility within SAP BTP. Designed and developed CPI flows, APIs, custom workflows, tailored applications, and system customizations in close collaboration with the customer and an external team.

Responsible for consulting, architecture, and solution design for a supplier portal built on SAP CAP and UI5, integrated with existing third-party APIs. Designed following a microservices approach, the portal ensures scalability and flexibility. A key feature was the automated user onboarding process, triggered by the creation of a new SAP Ariba contract, leveraging Ariba APIs and the Identity Authentication Service (iAS) API for seamless user invitation and management. The project was implemented in close collaboration with the customer and external development teams.

Led the architecture and development of a supplier risk backend service, integrating risk data from a third-party solution into SAP Ariba. The service enabled automated risk status updates for suppliers via Ariba APIs. A custom job scheduler, Ariba, and third-party connectors were developed following a microservices approach and securely connected via XSUAA. The solution ensured reliable risk data synchronization and compliance monitoring, designed and implemented in close collaboration with internal and external teams.
Solution Architect for Supplier Onboarding Integration
Responsible for designing and implementing the integration of SAP BTP, Master Data Governance (MDG), and external supplier onboarding processes via SAP iAS. The project focused on building multiple backend services with a microservices and multitenancy approach, ensuring secure connections between internal and external applications. A dedicated application router was used to manage authentication and access to UI5- and Vue-based onboarding applications, improving process efficiency and security.
