Research Engineer

About me

I enjoy the sweet spot between research and hands-on engineering. I’ve worked on a variety of projects in the higher education industry as well as in small to very large companies. For example, I had the honor to work at Google UK, the Decentralized and Distributed Systems lab at the Swiss Federal Institute of Technology (EPFL) led by Prof Bryan Ford, the Fraunhofer Institute for Algorithms and Scientific Computing (SCAI), and the University of Bonn.

Feel free to contact me for my CV, references, or any other request.
