UzbekistanWhat I'm looking for
I’m a Senior Flutter Engineer with 5+ years building high-scale, production-grade mobile and cross-platform applications used by 30M+ users. I specialize in clean architecture, BLoC/Riverpod state management, and REST/GraphQL API integration.
In streaming and travel/booking domains, I’ve delivered complex features with distributed international teams, maintained a 99.9% crash-free rate, and architected real-time booking and scheduling for a Fortune 500 hotel chain. I also optimize performance through profiling (Flutter DevTools), lazy loading, and adaptive caching to improve retention.
I build reliable delivery pipelines by leading CI/CD automation with GitHub Actions and Fastlane, and I reduce release friction by moving to on-demand deploys with zero manual App Store steps. I mentor teams and set reusable UI component/feature libraries that cut development time by ~30% while improving quality through testing and TDD.
