since fall 2010: sound producer at Akademickie Radio Kampus 97,1 FM - around 120 hours of weekend volounteering per year creating uncountable value of making the best non-commercial local radio station in Warsaw,

creator of my "swimming pool" playlist on YT (if I were a musical chief of a radio station played on outdoor swimming pool / gym, it would sound like this),

some other playlists containing older music (mainly 80s) are available too,

I also sometimes upload some links on my musical blog on Facebook,

in early 2000s (2001-2004, revival: 2008-2018): creator of my website about radio - this was probably the first Polish website to describe the Sporadic E propagation phenomenon,

photographer of Warsaw landscapes -> see my "Warszawa w Zoomie" blog on fotolog.pl (deprecated) and on Facebook, newer photos on my Instagram),

(since 2012) Linux user (after years of using Ubuntu at first, then Debian, Kubuntu, Manjaro and openSUSE TW/Leap, currently I use Ubuntu 20.04 LTS KDE + Rocky Linux 9 on QEMU VM + I have a Linux-based firmware on my router with my own custom local DNS server config),

keen swimmer, gym lover and cyclist and bachata dancer (hear my bachata playlist to feel like being on bachata party).
