Alex Osuya

With 6+ years of hands-on Flutter development experience, I specialize in building and deploying high-performance Android and iOS applications using Flutter and Dart. My expertise includes state management (Provider, BLoC, Riverpod, GetX), REST API integrations, Firebase services, and advanced UI/UX development to create smooth, efficient, and visually appealing applications. I have successfully published multiple applications on the Google Play Store and App Store and have experience setting up CI/CD pipelines using GitHub Actions and Codemagic to streamline app builds and deployments.

I focus on performance, scalability, and delivering a seamless user experience. Beyond development, I excel in collaborating with cross-functional teams, solving complex technical challenges, and ensuring that applications meet the highest standards. I actively integrate GitHub assets and third-party services to enhance app functionality and continuously explore new technologies to refine and optimize mobile solutions.

Driven by a passion for innovation and user-centric design, I stay up to date with the latest industry trends and best practices. I'm always looking for opportunities to work on challenging, high-impact projects that push the boundaries of what's possible with Flutter.
