SAP BTP & Integration Suite (CPI)
Design and implementation of complete SAP BTP integration scenarios end-to-end: CPI iFlows with Groovy transformation, Integration Advisor MIG/MAG for IDoc mapping, CAP extensions with CDS Views and OData V4, and API Management with OAuth2. Experience with Alert Notification Service, JMS Queues (Exactly-Once), and Edge Integration Cell.
AI & Machine Learning Stack
Development and deployment of production AI systems including RAG pipelines with LangChain and ChromaDB, 20+ agentic workflows using OpenAI and Claude APIs with tool use and output validation. Expertise in prompt engineering, guardrails, n8n agentic workflows, and Azure ML basics.
Python & Backend Development
Production-grade Python development with FastAPI, Pydantic, and SQLAlchemy. Experience building REST backends, CI/CD pipelines in Bitbucket and GitHub Actions, integration tests for hardware interfaces, and IoT backends with PostgreSQL and Docker Swarm.
SAP PI/PO
Hands-on experience with SAP PI/PO on-premise, including IDoc handling (ORDERS, INVOIC), RFC, SOAP and FILE adapters, Alert Framework, and Eclipse ADT for hybrid integration architectures.
SAP Development (ABAP Cloud / RAP / CAP)
Development with ABAP Cloud and RAP, CDS Views and OData V4, CAP using Node.js and Java, SAP Fiori and UI5 basics, S/4HANA integration, and SAP HANA Cloud basics.
TypeScript & React Frontend
Development of React/TypeScript frontends for internal engineering tools, including integration with REST backends and CI/CD pipelines in Scrum team environments.
Docker & DevOps
Containerization with Docker and Docker Swarm, CI/CD automation with GitHub Actions and Bitbucket Pipelines, monitoring with Prometheus and Grafana, and infrastructure tooling with Bash and Linux.
Embedded Systems & Firmware
Firmware development in C for ARM Cortex-M microcontrollers, SPI/UART drivers, PCB design with Altium, hardware bring-up, and CAN-Bus data analysis with Python.
Databases & APIs
Experience with PostgreSQL, SQLAlchemy, ChromaDB and FAISS as vector databases, REST APIs, Webhooks, and OData V4 services for enterprise and AI applications.

Projekthistorie
End-to-end integration: external REST API to CPI iFlow (routing, error handling, retry, JMS Exactly-Once) to S/4HANA SalesOrder via IDoc. Groovy script: JSON to SalesOrder/IDoc payload transformation, dynamic header setting, conditional routing. Integration Advisor MIG for IDoc ORDERS05, MAG for JSON-to-IDoc field mapping. API Management: OAuth2 client credentials, rate limiting, external API proxy. Alert Notification Service on error threshold. CAP extension: CDS data model with @UI annotations, OData V4 service via RAP Service Binding, HTML5 monitoring dashboard with real-time order status and manual retry.
Hybrid architecture: SAP PI/PO for legacy ERP IDoc communication (ORDERS, INVOIC) via RFC and SOAP adapters in Eclipse ADT - BTP Integration Suite for modern REST/OData interfaces. JMS queues for Exactly-Once delivery. Alert Framework for operational monitoring. 3 failure scenarios documented with root cause and resolution. Full architecture document: message flows, security concept, deployment architecture, operating manual.
Full RAG pipeline: document ingestion, chunking (800 chars, 150 overlap), OpenAI embeddings, ChromaDB/FAISS vector storage, retrieval chain. Confidence threshold 0.75 - below it returns insufficient context instead of hallucinating. 50-question eval set. Sub-2s latency at 500+ docs, 90%+ accuracy.
