What I'm looking for

I’m looking for a Senior Android role where I can build and scale production-ready mobile features using modern Kotlin and Jetpack. I’m open to global remote work, and I focus on Clean Architecture, reliable testing, and smooth CI/CD.

I’m a Senior Android Engineer with 10+ years of experience building, maintaining, and scaling Android applications across the full software development lifecycle. I deliver Android features from technical design through production release, partnering closely with product, backend, and QA to ship reliable, API-driven experiences.

My expertise centers on Kotlin and modern Android engineering practices—especially Jetpack Compose, Clean Architecture, MVVM, and reactive state management. I’ve led end-to-end feature work, implemented scalable modular solutions, and handled production support by diagnosing and resolving issues to improve stability and user experience.

Most recently, I completed a production-oriented engineering project focused on Offline-First Architecture, Room as Single Source of Truth (SSOT), Paging 3 with RemoteMediator, and WorkManager synchronization. I built automated testing and CI/CD with GitHub Actions and Firebase App Distribution, and I continuously strengthen maintainability through release engineering, performance improvements, and tooling.
