The in-depth knowledge and the examples

Ankur Kapila - Deutsche Bank

Course - Programming with Kotlin

Alex is a very friendly, personable guy. He made everyone feel comfortable working through together and volunteering to give slutions.

Kai Bergman - Red Embedded Consulting Sp. z o.o.

Course - Kotlin for Beginners

Intensity of a course, coverage of topics. Complicated topics are explained on a good level, so even though there are some white spots left in of them (like DSL) -- it won't be hard to go on by myself as I already have a common understanding of basis and at least know how to form my questions to Google.
