AI Engineer for LLM agents, private LLMs and Python backends
Austria
German, Croatian, English
About me
I build LLM systems that run in production: agents with tool calling, RAG over your own documents, and self-hosted open-weight models (llama.cpp, sglang) so sensitive data stays on your own servers. Right now I'm building AI coding of medical documents for Austrian hospitals and an AI report generator for energy audits. Background: MSc in financial and actuarial mathematics (TU Wien), about 9 years as a software engineer at IBM and Zurich Insurance, in insurance and finance. Python, Rust, Java, TypeScript. Clear scope, fixed price, clean handover.
