Sunil Kumar Android, Kotlin Multiplatform & Backend Developer
No reviews yet

My teaching style is architectural, hands-on, and ecosystem-centric. I don’t just teach syntax; I teach how to build scalable, end-to-end solutions using the Full-Stack Kotlin power.

I bridge the gap between the Ktor backend, Shared KMP logic, and Modern Android UI (Compose) by focusing on "Code Once, Run Everywhere." Through project-driven learning, I demystify complex concepts like Coroutines, Flow, and Dependency Injection. By breaking down the "Expect/Actual" pattern and Clean Architecture, I empower developers to write modular, testable code that lives comfortably on any server and thrives on every device. Clear, visual, and always practical.
