Over time, I have contributed several features and enhancements to the Eigen linear algebra library:
I am a core TensorFlow contributor. As such I worked on too many aspects of the system to list here.
As former project lead, I contributed to the source code of the famed VLC media player which is available in this VLC git repository. I was also the main contributor to the videolan server (aka VLS). The VLS is now defunct, as its functionality has been merged into the VLC. The source code is however still available in the VLS svn repository.
