About Me

Welcome to my website!
I am Stefan Haller, born in 1992 in Germany.
As of late 2022, I have been part of the team at rabbit AI. Prior to that, I worked as a researcher in computer science at the Computer Vision and Learning Lab of the Ruprecht-Karls-University Heidelberg. My areas of expertise include optimization techniques for machine learning, machine learning in general, and computer vision.
Beyond that, I am also enthusiastic about experimenting with different programming languages, tools, and technologies. In my free time, you can find me hacking and coding. I am also a firm believer in the power of free and open-source software.
Feel free to check out my GitHub profile (though I do not always get the opportunity to hack something as often as I would like!).
If you want to reach out, just shoot me an e-mail.
