If you’re a mid-level developer, you probably have a solid grasp of Kotlin basics, coroutines, and maybe even some experience with Flows. But if you’ve ever struggled with integrating legacy […]
Serialization isn’t just about libraries like kotlinx.serialization or Jackson; it’s intertwined with Kotlin’s syntax and semantics. In this post, we’ll explore how Kotlin’s design choices impact serialization, with real-world implications […]
If you’ve ever dealt with algebraic data types in other languages or wanted to model closed hierarchies without the fear of missing cases, this is for you. We’ll cover everything […]
As a senior Kotlin developer with over a decade of experience in JVM-based languages, I’ve seen how Kotlin’s functional programming features can transform code from verbose and error-prone to concise […]
Kotlin offers several class abstractions that go beyond traditional object-oriented classes. Understanding these can help you write more efficient, readable, and maintainable code. We’ll explore their internals, JVM representations, and […]
If you’re a middle dev, you probably use val and var daily, but have you ever wondered why Kotlin doesn’t have traditional fields like Java? Or how to avoid those […]
In this blog post, we’ll dive deep into delegation in Kotlin. If you’re a mid-level developer familiar with Kotlin basics but wanting to level up your understanding of advanced features, […]
If Kotlin’s nullability system is about local correctness, then generics are about compositional correctness.They define how types relate across abstraction boundaries, where misuse quickly turns into either unsafe APIs or […]
Kotlin Coroutines are powerful, flexible, and expressive. They make asynchronous programming easier than older techniques like callbacks, AsyncTask, or RxJava. But like any concurrency tool, coroutines can become slow, inefficient, […]
Testing coroutine-based code is one of the most important skills for Android and Kotlin developers. Coroutines introduce asynchronous execution, background work, Flow streams, delays, and lifecycle–all of which make testing […]
