Tim Felgentreff
Tim Felgentreff is the language development lead for GraalPy, the Python implementation on the GraalVM. He has been involved with the PyPy/RPython project and various other dynamic language VMs since 2007. Tim also keeps in touch with the Software Architecture Group in the Hasso Plattner Institute at the University of Potsdam where he received his doctoral degree in 2017.
