Hi, I’m Zain Shakeel. I’m a Flutter Developer with 5+ years of experience building cross-platform mobile apps, scalable architectures, and high-performance UIs.
I specialize in Dart, Flutter, Firebase, REST APIs, and state management with GetX, BLoC, and Provider, and I also work with Kotlin and Jetpack Compose on Android. I enjoy mentoring teams, leading features end-to-end, and delivering production-ready, maintainable apps.
