About

I’m a Python and C#/.NET backend and AI/ML engineer based in Munich, and I love building production-ready systems that combine solid software engineering with modern machine learning. My recent work focuses on LLM- and NLP-integrated applications, where I design the core logic and REST APIs, wire up model providers like OpenAI and Hugging Face, and iterate on prompt strategies to improve feedback quality and consistency.

Across my experience, I’ve also designed MSSQL databases from scratch and optimized performance in real, large-scale .NET systems. I enjoy taking projects end-to-end—containerizing stacks with Docker, profiling bottlenecks, and delivering reliable features through the full SDLC in collaborative Scrum environments. I’m currently completing my M.Sc. in Informatics at TUM and continue to deepen my expertise in LLM integration, PyTorch-based modeling, and high-performance backend development.
