Years AI/ML

I'm a physicist turned AI/ML Engineer with a passion for transforming complex scientific problems into elegant software solutions. My journey from experimental physics to AI engineering has given me a unique perspective on building intelligent systems.

With 8+ years of programming experience, including 5+ years specializing in Python and 3 years focused on AI/ML, I've worked on everything from automating laboratory measurements (achieving a 1000x speed improvement) to building production-grade LLM applications with RAG pipelines.

Recently, I completed intensive DevOps training to strengthen my cloud infrastructure skills, focusing on AWS, Azure, Kubernetes, and modern CI/CD practices. I excel in fast-paced environments where I can take ownership of challenges while contributing to team success. My background in physics research has taught me to approach problems systematically, validate hypotheses rigorously, and communicate complex ideas clearly.

Beyond technology, I'm deeply involved in community leadership. As Vice President Public Relations at Toastmasters Berlin, I hone my communication skills and participate in speech contests. I'm also an active tournament chess player, serving as a referee in the German Oberliga and coaching youth players. These experiences have sharpened my strategic thinking, patience, and ability to stay calm under pressure—skills that translate directly to software engineering.
