I'm a Masters student in Computer Science at the University of Vienna, currently interested in backdoor attacks on language models in Federated Learning. At the same time, I'm also interested in a broader view on AI, taking into account the ethical, legal, and social implications from its development and usage.

With a Bachelor's degree in Internet Computing from the University of Passau, Germany, I've also worked as a web developer, software engineer and as a lecturer, imparting programming skills to non-computer science students. For the last few years, I've also consulted, implemented and integrated customized software projects for a variety of different clients.

I find joy in creating music, capturing moments through film, and reading and contributing to Wikipedia (en, de). I'm also a French language learner, hobby chef and an avid explorer who enjoys discovering new things about the world.

Feel free to reach out if you are interested in collaborations or have exciting topics to discuss. I'm currently based in Vienna, Austria.

Digital Garden

Here are some of the things I've worked on or thought about.

This is not a blog but rather a collection of digital artifacts from different sources. Some of them are contract work, others are private projects or imperfect notes, essays, and ideas growing slowly over time.




You can expect irregularly published notes on current world events, memes, short stories, Wikipedia articles and essays from various renowned guest writers.
