SAP BTP Developer at Capgemini (2025-08 – Present)

Client: Coca Cola

• Built Cross-System AI Chatbot (SID): Created a chatbot that interprets user prompts to automate CRUD workflows across SAP S/4HANA, SuccessFactors, and ServiceNow systems.
• Integrated S/4HANA & SuccessFactors: Connected the CAP application to 20+ external SAP and third-party systems using cds.connect.to(), SAP Cloud SDK, and OData/REST service definitions.

• Implemented Human-in-the-Loop (HITL): Developed a deterministic pause-and-resume state machine that interrupts LLM execution to render interactive verification forms for critical CRUD operations.
• Secured Microservices via XSUAA: Configured route and service-level authorization using SAP AppRouter, XSUAA (OAuth 2.0), and JWT token forwarding to enable secure data exchange.
• Developed Context-Aware Memory & RAG: Built a long-term user memory module stored on SAP HANA Cloud DB and integrated Azure AI Search to inject SAP configuration rules (MM/SD/PP) via RAG.
