Welcome to my corner of the interwebs!

People call me Grisha, 0xa, or oxapentane, take your pick.

During the day I'm tinkering around the labs of Institute of Physics, University of Amsterdam. Outside of this I like to play with radio and look at the large-scale infrastructure. For example look at the traffic light thing we did couple of years ago. Also, I like build, break, and rebuild again my home infrastructure, which is now is running on NixOS again.

If you haven't got it yet, most of the time you'll find me staring into my 'puter
