About

Native Android, built with care

I'm a Motivated Mobile Application Developer specializing in native Android development with Kotlin, currently building production travel and outdoor-activity apps. I work across MVVM architecture, Firebase (Auth, Realtime Database, Firestore, Storage), REST API integration, and clean, intuitive UI/UX.

I'm comfortable across the full mobile lifecycle — UI design in Figma, debugging, performance optimization — and I actively use AI-assisted development workflows to move fast without cutting corners on code quality. I'm currently seeking freelance mobile projects where strong Android fundamentals drive measurable results.
