Anselm Kruis works as a Senior Solution Architect for science + computing ag, a Bull subsidiary. He started software development 25 years ago and enjoys the simplicity of Python since nearly 10 years, mostly using Jython and nowadays Stackless Python. If allowed by professional constraints, he is happy to utilise and contribute to open software projects. Currently he leads the development of flowGuide2, a novel tool to implement CAE-related simulation processes in large scale HPC environments. Of course, one cornerstone of this project is Python.
