SENIOR MOBILE FLUTTER DEVELOPER
Senior Mobile Flutter Developer with over 7 years of experience building scalable, high-performance cross-platform
applications for Android and iOS. Seeking to leverage expertise in Flutter architecture, API integration, performance optimization,
and CI/CD practices to lead development initiatives and deliver intuitive, reliable mobile experiences. Aims to mentor teams, drive
technical excellence, and collaborate with product and backend stakeholders to create secure, maintainable, and business-
impacting mobile solutions.

PROFILE SUMMARY
• Cross-Platform Application Architecture: Design and develop scalable Flutter applications for Android and iOS using
clean architecture and modular design principles.
• State Management & Performance Optimization: Implement efficient state management solutions (Bloc, Provider,
Riverpod) and optimize app performance, responsiveness, and memory usage.
• API Integration & Backend Collaboration: Integrate RESTful APIs and collaborate with backend teams to ensure secure,
reliable, and seamless data communication.
• CI/CD & DevOps Integration: Manage build pipelines, automate deployments, and integrate CI/CD workflows to enable
faster and stable releases.
• Code Quality & Technical Leadership: Conduct code reviews, enforce best practices, mentor developers, and drive
adherence to SOLID principles and design standards.
• Agile Delivery & Stakeholder Collaboration: Work within Agile/Scrum frameworks, translating business requirements
into technical solutions while coordinating with cross-functional teams.

NOTABLE CAREER ACCOMPLISHMENTS
• Led the transition of a legacy mobile codebase to Flutter Clean Architecture, resulting in a 40% reduction in technical debt
and a 25% faster feature delivery cycle for subsequent sprints.
• Identified and resolved critical rendering bottlenecks by implementing the Impeller engine and custom repainting
boundaries. Achieved a consistent 60fps performance and led to a 15% increase in Play Store/App Store ratings.
• Implemented a global BLoC-based state management system across a multi-module enterprise app. Reduced memory
consumption by 20% and eliminated 95% of state-related crashes reported in Firebase Crashlytics.
• Designed and integrated Codemagic and Fastlane pipelines, automating the build, test, and deployment process. Reduced
the "code-to-store" deployment time by 70%, saving approximately 10 engineering hours per week.
• Revamped the API integration layer using Dio and Interceptors to handle complex JWT authentication and encrypted local
storage. Cleared a third-party security audit with zero high-severity vulnerabilities found in the mobile front-end.
