In spare time, I'm engaged in development of my small web app of online radio, and also I spend time maintaining my small pet projects (scripts for daily routine) to learn and hone my skills as software (web) developer in practice. Regular reading various documentation and articles as essential part of learning process will help me (I hope) in future job interviews.
Part of my projects are available on GitHub. Maybe, someday I'll create a separate section with my projects on this website.
For joy and pleasure, I like watching (listening) stand-up comedy. Before sleep, I watch YouTube videos about technologies and how things work. When I'm cooking I listen to podcasts: Luke's English Podcast, Web Standards (RU), ShopTalk, Off The Main Thread.
I really like doing music mixes. Once or twice a quarter, I compile a new one and record it. After that I publish it on my social media. You can check the archive on my PromoDJ space.
