About Me

Hi! I'm a Data & ML Engineer currently working at SWISS International Airlines, where I build scalable data pipelines for various business units and design cloud-based data platforms. I completed my MSc at ETH Zürich. In my Thesis, I developed a novel fault-tolerant framework for large-scale LLM training in dynamic environments.

I love throwing myself into solving complex problems and building systems that create real-world impact. My current focus areas include agentic systems and MLOps for production environments.

Beyond work, I enjoy mentoring students & contributing to diversity and inclusion initiatives. Outside of that, you'll usually find me in the mountains ⛰️ or discovering new places.
