Flutter Developer | QA-Focused Mobile App Specialist

I build reliable, production-ready Flutter applications that are designed to perform well long after they're launched. My QA background helps me catch issues before your users do, resulting in smoother releases, fewer bugs, and lower maintenance costs. Using Flutter, Firebase, REST APIs, BLoC/Cubit, and clean architecture, I develop scalable mobile applications that are fast, maintainable, and built for real-world use. Unlike many developers who focus only on implementation, I also validate user flows, investigate edge cases, reproduce bugs, and thoroughly test every feature before release. This development-first, QA-focused approach helps deliver polished apps that users can rely on. I've worked on mobile applications across multiple industries, including: • Logistics & Transportation • Renewable Energy • Service Marketplaces • Business & Productivity Solutions Core Flutter Development ✅ Flutter App Development ✅ Firebase Integration ✅ REST API Integration ✅ BLoC / Cubit State Management ✅ Clean Architecture ✅ Performance Optimization ✅ Bug Fixing & Feature Development ✅ App Store & Google Play Deployment Quality Assurance ✅ Mobile App Testing ✅ Functional & Regression Testing ✅ UX & User Flow Validation ✅ Edge Case Testing ✅ Detailed Bug Reports with Screenshots & Screen Recordings Whether you need a Flutter developer to build a new application, improve an existing product, fix complex issues, or thoroughly test your app before release, I can help you deliver a stable, high-quality mobile experience with confidence.
