Piotr’s just like a super friendly guy who’s really passionate about these topics that he’s teaching. He’s really good at distilling these topics down into a very clear explanation of the underlying tools and technologies.

I strongly recommend these course of Kotlin to everybody who is interested in learning to code, people like Piotr are out there creating learning resources for all of us.

Thanks to codersee what taught me real world concepts which I use in my day to day job.
