I have experience delivering a variety of projects — from hybrid to fully native mobile applications.️ I work with multiple frameworks and languages including React Native, Flutter, Swift, and Kotlin, and I also cover backend needs using Node.js, Python, C#, and Java. I take on both full-cycle development — from idea to App Store / Google Play launch — and smaller projects or specific parts of the work.
