I'm originally from Prague (the capital city of Czech republic in central Europe) but I'm currently employed as a software development engineer at Amazon Instant Video in London. I'm working on video playback component for living room devices. A lot of interesting stuff related to adaptive streaming, video and audio encoding and DRM. Most of the time I'm using low level C++ and Linux and occasionally Python for some internal tools.
You can find plenty of my answers related to c#, .net, entity-framework and wcf but I almost didn't use those technologies since I joined Amazon in 2013 so I rather don't try answering related questions any more.
