What will you learn?
During the Kotlin Professional Developer training, you will learn:
You will learn all the functional programming features Kotlin offers, how to use them as generic building blocks (higher-order functions) and as a means to scope your code for extra conciseness and readability.
Get to know how Kotlin helps you designing slick Domain Specific Languages (DSL’s) using various Kotlin features like operators, Extensions, Type-Safe builders and ContextReceivers.
You will learn how to use Kotlin in an idiomatic way making use of immutability, expression-oriented, and scoped constructs so that you can unleash Kotlin’s true power
The last part will be dedicated to Kotlin’s mind-rocking concurrency features Coroutines. You will get to know their benefits and how they work under the hood so that you can write and test concurrent/parallel code in a snap.
Learn how to use advanced language features like Delegates, advanced Generics, ContextReceivers and where to apply them best

In two immersive days, individuals gain the fluency, frameworks, and confidence to put AI to work. Not just in theory, but in the flow of the actual day-to-day.
Most AI initiatives never make it past the pilot phase. Hype burns hot, priorities shift, and promising projects stall out before delivering business value.
AI is no longer optional—it’s becoming an essential skill for today’s Product Owners. From discovery to delivery, Artificial Intelligence is reshaping how we define value, validate ideas, and build the right products faster.
