Amrendra Singh

Results-driven Senior Flutter Developer with 6+ years of end-to-end experience designing, developing, testing, and deploying high-performance cross-platform mobile applications for Android and iOS across fintech, enterprise, and media domains. Deep expertise in Dart programming language, Flutter SDK, and Flutter framework — with hands-on mastery of dependency injection patterns in a modularised architecture (GetIt), enabling clean, well-documented, maintainable code and comprehensive unit test case coverage. Skilled at converting wireframes into pixel-perfect, responsive mobile screens with adaptive UI behaviour across screen sizes and Flutter versions.

Strong command of state management (BLoC preferred, Provider, Riverpod, GetX), web services integration (REST, SOAP, JSON, XML), and Flutter packages including networking (Dio), local storage (Hive, SQFLite), security/cryptography, and location services. Experienced in the full mobile development lifecycle — from client engagement, analytical reasoning, and effort estimation through implementation, code reviews, and Play Store/App Store deployment. Excellent communication skills with a proven track record of explaining code logic to team members, collaborating in Agile/Scrum teams, and delivering projects on time.

Proficient in Android Studio, Xcode, VS Code, CI/CD pipelines, and AI-assisted development using GitHub Copilot.
