For the past couple of years I've been doing random things, including embedded development, "modern" system administration, web/backend development and (a tiny bit of) hardware design, involving various technologies, such as Bluetooth Low Energy, embedded Linux (inc. buildroot), cryptocurrencies, Python and more. Currently based in Warsaw, Poland.
I am a founding member (and a member of the board for some time now) of Warsaw Hackerspace.
I am somewhat active on some social networking sites, such as twitter or github.
I sometimes write about things I do on my blog, but not much lately.
