Senior Android developer focused on clean architecture, scalable apps, and Kotlin Coroutines.

What I'm looking for

I want to build and ship scalable Android apps with clean architecture, modern UI (Jetpack Compose), and Kotlin Coroutines, taking full feature ownership to improve stability, UX, and user feedback with a strong engineering mindset.

I’m a Senior Android Developer with 7+ years of experience building and shipping scalable Android applications from scratch to production. I’m known for clean architecture, maintainable code, modern UI development, and asynchronous programming in Kotlin.

At Lectera, I led the migration of the core application from RxJava to Kotlin Coroutines & Flow, simplifying asynchronous code and reducing boilerplate by ~20%. I also transitioned Media2 to Media3 to improve video playback stability, increased application stability to 98–99% crash-free sessions, and improved Google Play user rating by approximately 1 star through continuous UX improvements and bug resolution.

Across my roles, I’ve taken full ownership of entire apps as a sole Android developer and led feature/module ownership inside Android teams of 10+ developers. From building a production-ready Jetpack Compose app with Billing and Google/Huawei services to developing custom push notification handling, I focus on end-to-end delivery, reliability, and user impact.
