I've built and maintained native Android applications at Elsner Technologies using Kotlin and Java, applying MVVM, Clean Architecture, SOLID principles, Jetpack Compose, Coroutines, and Flow.
I developed inventory, healthcare, document scanning, scheduling, and monitoring products, including Stockware with real-time stock updates and O-Health with chat, video consultations, appointments, and push notifications.
I integrate REST APIs, Firebase, WebSockets, Agora, Mapbox, RoomDB, SQLite, and WorkManager to deliver responsive, maintainable Android experiences from UI implementation through testing and deployment.
