Who I am
I am a strongly web-oriented full-stack software developer and IT trainer.
Senior Software Engineer at Atlassian.
One of hosts of Śniadanie z Programowaniem by JustJoin It breakfast show.
TypeScript fan and promoter. I talk about web and stuff.
I believe that teaching others and sharing knowledge make us better developers.
