I am a software engineer with ample experience with c# and c++, almost exclusively on the windows platform. I live in the netherlands, where I work at 3mensio medical imaging.
My software engineering has been focused on medical workstations (2D and 3D).
I write open source sofware mostly on my own, mostly because the projects are ideas that I had and wanted try out. CharLS is there because I wanted to popularize the lean and mean JPEG-LS standard, hopefully at the expense of JPEG 2000, which is slow, large and overengineered. It also was a nice playground to experiment with C++ optimization techniques using traits.
I wrote pageturner because I felt that onscreen reading of PDF was not currently the experience it could be, more interactive for more productivity, and with smooth animations to make it easy on the eyes.
