I hold an M.Sc. in Physics and a Ph.D. (summa cum laude) in Machine Learning from Technical University Munich, Germany's top rated university. During my studies I gathered a broad mathematical background and acquired strong programming skills in C++, Python, MATLAB and F#. I have worked with all ranges of systems, from 8-bit microcontrollers to massively parallel SIMD multiprocessors. I have expertise in control engineering, data processing and analysis, state-of-the-art machine learning, systems programming and professional administration of both Linux and Windows systems. Given my background I pay particular attention to the correctness, reliability and scalability of my work. I enjoy being part of teams that create effective solutions for complex problems while maintaining open and friendly communications. My working hours are pretty flexible and I am happy to join existing teams of freelancers working for you.
