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

Course - Kotlin for Beginners

It was concise, well organised, had nice balance of tasks and lectures and everything was on point.

Alexander Illarionov - C.T.Co SIA

Course - Advanced Kotlin Programming

Great content, excellent exercises. Covered a lot of information. Friendly to new Kotlin programmers but also a lot to still learn for those of us already using Kotlin. Highly recommend this course. The pace of the course was perfect, not too slow, not too fast. Alternating between instruction and exercises helped cement the knowledge from each section.
