What I'm looking for

I seek roles building high-impact cross-platform mobile apps where I can drive performance, UI/UX quality, and mentor teams while working with modern CI/CD pipelines and scalable architectures.

I am a Flutter developer with 5+ years of hands-on experience building and deploying high-performance Android and iOS applications using Flutter and Dart. I specialize in state management (Provider, BLoC, Riverpod, GetX), REST API and Firebase integrations, CI/CD with GitHub Actions and Codemagic, and advanced UI/UX and animations to deliver scalable, performant apps.

I have published multiple apps to the Google Play Store and App Store, launched a cross-platform app that reached over 2,000 active users in its first month, and mentored junior developers while collaborating with cross-functional teams to solve complex technical challenges. I focus on performance, security, and user-centric design, and continuously adopt new technologies to improve product quality.
