About Bartosz Zaczyński

GitHub

My name is Bartosz. I’m a bootcamp instructor, author, and polyglot programmer in love with Python. I help my students get into software engineering through lectures and mentoring.

I’m a seasoned developer with over a decade of commercial experience and another decade of coding as a passion. During my professional career, I worked for big and recognizable names, but also for medium-sized software houses and a few start-ups.
