Hi, I’m a dedicated Android & iOS developer with 3 years of experience building practical, user-friendly apps. I specialize in Java, Kotlin and the Android SDK, and I follow best practices using MVVM architecture, Firebase, and REST APIs. 😎 In addition to native Android development, I have strong experience in cross-platform app development using Flutter and FlutterFlow. I’ve built and deployed scalable apps for both platforms, integrating Firebase services like Authentication, Firestore, Cloud Messaging, and Analytics to power real-time, secure, and engaging user experiences.
