Kotlin Coroutines Under the Hood - Dispatchers, Thread Pools, and Work Stealing

Sat, 21 Feb 2026 00:00:00 +0530

Prerequisites and assumptions

Note: This article reflects how the kotlinx.coroutines scheduler works as of February 2026. Internal implementation details can change between releases.

You have written Kotlin coroutines before. You know what launch, async, withContext, and suspend do at a basic level. You’ve used Dispatchers.Default, Dispatchers.IO, and Dispatchers.Main in at least one project. This article is about the machinery underneath those abstractions.

Agentic AI in 2026 - A Thinking Engineer's Field Guide

Sun, 11 Jan 2026 00:00:00 +0530

The paradigm shift in programming

We’re living through one of the most significant transformations in how software gets written. The rise of Agentic AI has changed everything about the engineer’s experience. Gone are the days when AI assistance meant autocomplete suggestions or simple code snippets. Today’s AI agents can reason about codebases, execute multi-step tasks, browse documentation, and iterate on solutions autonomously.

Kotlin's Plugin Discovery - Service Provider Interface Explained

Sun, 05 Oct 2025 10:00:00 +0530

Prerequisites and assumptions

You are working with Kotlin on the JVM or Kotlin Multiplatform. You understand basic interfaces and classloading concepts. You have encountered scenarios where you want pluggable implementations without hardcoding dependencies.

Good reads and references

Source code: java.util.ServiceLoader in the JDK

What you get with SPI

The Service Provider Interface is a built-in JVM mechanism introduced in Java 6 for discovering and loading implementations at runtime. It’s a registry where libraries announce “I provide an implementation of X” and applications ask “give me all implementations of X” without either side knowing concrete class names at compile time.

Four Doors, One Party - K/N, JNI, JNA & FFM

Sat, 13 Sep 2025 17:00:00 +0530

Think of native power as a party. Kotlin can show up through four different doors: Kotlin/Native (K/N), JNI, JNA and FFM. Same venue, different guest lists. This guide explains which door to use, when and why.

What changes by door? Mostly the runtime you stand in, call overhead, memory rules, tooling and portability.

From Source to Sorcery - Kotlin Native's Interop Magic

Fri, 05 Sep 2025 16:05:00 +0530

Prerequisites and assumptions

You are using the Kotlin Gradle DSL and the Kotlin Multiplatform plugin. You have a working C toolchain per OS. On macOS install Xcode command line tools or Homebrew. On Linux install GCC or Clang and the development headers for the libraries you plan to use. On Windows install MSYS2 with MinGW and ensure gcc and pkg config are in PATH.

Detekt 🔍

Detekt is a static code analysis tool, but it does a lot more than that, from being able to add your own custom rule to formatting your code (internally uses ktlint). It’s especially useful tool for when you are working on a large project or with a team and you need to ensure uniformity across code development setup.

My Technology Stack

My Technology Stack

Over the years as an Android developer, I’ve worked with various technologies, frameworks, and architectural patterns. Here’s an overview of my current technology stack and the tools I use in my day-to-day development.

Programming Languages

Kotlin

My primary language for Android development. Kotlin’s concise syntax, null safety, and interoperability with Java make it an excellent choice for modern Android applications.

AlarmManager for Android Oreo and above

Tue, 05 Jan 2021 18:30:00 +0000

Android is getting mature with every major release and we are heading towards more user-centric and privacy first Operating System.

Android Oreo was released back in 2018, one of the major changes were related to background limitations which changed the way most apps would function. It was one of the turning points for android, as a lot of apps were running in the background even without users knowing about it and this also drained a lot of battery, to prevent that from happening to a certain extent the android team came up with this major change.
