FLUTTER DEVELOPER — 2 YEARS EXPERIENCE

• Designed and developed production-ready cross-platform mobile applications using Flutter and Dart, targeting both Android and iOS platforms with a shared, maintainable codebase.

• Translated UI/UX designs and product requirements into responsive, pixel-accurate interfaces, ensuring consistent layouts across different screen sizes and devices.

• Implemented scalable application architecture with clean separation between presentation, business logic, services, and data layers, making applications easier to maintain and extend.

• Integrated RESTful APIs for authentication, data retrieval, content management, AI-powered functionality, and other third-party services.

• Worked extensively with Firebase, including Firestore, Remote Config, Analytics, Crashlytics, Cloud Messaging, and other Firebase services for backend functionality, configuration management, analytics, and application monitoring.

• Implemented and managed state management solutions to maintain predictable application behavior and improve code organization.

• Integrated third-party SDKs and services while handling API responses, loading states, exceptions, permissions, connectivity issues, and edge cases.

• Developed interactive features including AI-powered workflows, media generation, image/video processing, dynamic content, animations, subscriptions/monetization components, and custom UI experiences.

• Focused on application performance by reducing unnecessary widget rebuilds, optimizing network operations, managing resources efficiently, and improving overall UI responsiveness.

• Implemented robust error handling and debugging workflows, identifying and resolving runtime, build, dependency, API, Firebase, and platform-specific issues.

• Worked with native Android and iOS configurations when required, including Gradle, CocoaPods, Info.plist, permissions, deployment configurations, and platform-specific integrations.

• Integrated advertising and monetization solutions, including Google Mobile Ads formats such as banner, interstitial, rewarded, and app-open advertisements.

• Managed application configuration through remote configuration, allowing API settings and feature controls to be updated without requiring frequent application releases.

• Followed Git-based development workflows for version control, feature development, debugging, code management, and release preparation.

• Tested applications across different devices and environments, identifying UI inconsistencies, functional issues, crashes, and performance bottlenecks before release.

• Prepared applications for Google Play Store and Apple App Store deployment, including release builds, configuration, versioning, and production troubleshooting.

• Collaborated with designers, backend developers, and other stakeholders to convert product ideas into functional, polished, and production-ready mobile experiences.
