What I'm looking for

I seek a mobile engineering role focused on Kotlin/Android development, hardware integrations, and scalable MVVM architecture in a collaborative, product-driven team where I can lead projects and grow technically.

I am an Android developer with hands-on experience leading development of a POS application used by over 30,000 clients, building robust local databases, hardware integrations, and maintainable MVVM architectures using Kotlin, Coroutines, Hilt, Room and Retrofit.

I deliver end-to-end solutions including serial device communication, payment protocol integration, CSV import, FTP-based remote updates and multi-language support, and I contribute actively to open-source projects and cross-platform apps while improving app performance and stability.
