Approach

Technically clear. Focused in execution.

I work on software where business requirements, technical complexity and real operating conditions meet. The focus is on clear architecture, robust implementation and solutions that fit into existing system landscapes.

Think in production terms

I do not build for demo scenarios. I build for systems that need to work reliably in daily operations: clear interfaces, stable services and maintainable integrations.

Connect business IT

A core strength is linking established SAP and enterprise landscapes with modern web and AI approaches without losing sight of the operational context.

Implement pragmatically

From SAPUI5 freestyle apps and CAP services to LLM, RAG and MCP workflows, I work in a structured and direct way with a focus on clean results instead of technical posturing.

Skills

A clean setup across enterprise and AI.

Solid SAP and frontend experience meets current topics such as RAG, embeddings and agentic integration. That enables fast delivery without technical arbitrariness.
