About me

My real name is Bartosz Jarzyna and my open source contributor nickname is bbrtj. I'm an experienced programmer with strong opinions held back by a good dose of humility. I mainly use Perl and Pascal to solve daily puzzles.

I write quite a lot of open source software in Perl. It can be found by following GitHub and MetaCPAN links in the banner at the top. You can help, too - see my support page.

About this website

This is a place for me to loosely express my thought - a minimalistic blog-like journal. There's no multilingualism, no user sessions, no searching, no clickbaits and no ads, and there will never be. All there is is minimalistic design and my written thought. Enjoy.
