Hi, I'm Léon

I'm a Computer Science Master's student in Berlin specializing in Natural Language Processing (NLP).
I build intelligent systems that understand and process human language.

👨‍💻 About Me

I am a Master's student at Humboldt-Universität zu Berlin with a profound passion for Artificial Intelligence. My journey has taken me from an initial degree in Computational Engineering to over two years of professional experience as a Full-Stack Developer at the Fraunhofer Institute (IPK), and now to a deep specialization in NLP. At Fraunhofer, I had the opportunity to contribute to high-impact projects, including developing the first prototype for the EU's digital battery passport.

My core interest lies in Transformers and Large Language Models. I thrive on reading research papers and working on projects that explore the frontiers of machine reasoning and language processing. I am currently working on my Master's Thesis and actively seeking a full-time role where I can apply my passion for Machine Learning and NLP.
