About Otyloine

Mobile developer specializing in Flutter for over three years, I design and develop high-performing, reliable, and scalable iOS and Android applications. I work on the entire product lifecycle: design, development, optimization, testing, and deployment to the stores.

I build fast, fluid, and stable apps with a clear architecture designed for longevity. My approach is centered on user experience and code quality to ensure solid performance, simple maintenance, and smooth future evolution.

Mastered Technologies: Flutter/Dart, Provider, Bloc, or Riverpod architectures as needed, Firebase (authentication, database, notifications, analytics, cloud functions), in-app purchases, performance management, and App Store and Play Store publishing.

I pay special attention to design consistency, performance, stability, and ease of use. My goal is always the same: to deliver a reliable application that is enjoyable to use and ready to scale from launch.
