Hire the Best Flutter Developers
in Bosnia and Herzegovina

Looking for a Flutter Developer who can turn your idea into a fast, polished, production-ready application? You’re in the right place. I’m a Senior Flutter Developer with 4+ years of professional experience building, maintaining, and scaling production applications for iOS, Android, and Web. Over the years, I’ve worked with startups and product teams on both new and existing products. I’m comfortable taking ownership of features, working through technical challenges, integrating APIs and third-party services, and improving architecture as an application grows. My experience includes consumer apps, healthcare platforms, AI-powered products, marketplaces, subscription-based applications, and media-heavy mobile experiences. What I can help you with • Flutter app development for iOS, Android, and Web • Building new features in existing Flutter applications • Taking ownership of features from requirements to implementation • Responsive and pixel-accurate UI implementation • REST API and third-party service integrations • Firebase and Supabase integrations • Authentication, push notifications, analytics, and deep linking • In-app purchases and subscription flows • Bug fixing, performance improvements, and codebase maintenance • App architecture, refactoring, and scalability improvements • App Store and Google Play production-ready development • AI-powered development workflows using Claude Code and Codex Technologies I work with • Flutter & Dart • Firebase: Auth, Firestore, Storage, Crashlytics, Remote Config, Messaging • Supabase • REST APIs • State Management: Provider, Riverpod, Bloc/Cubit, GetX • Analytics & SDK integrations • Git and collaborative development workflows • Claude Code and Codex for AI-assisted development Modern AI tools are also part of my development workflow. I use Claude Code and Codex where they can genuinely speed up implementation, debugging, code analysis, refactoring, and repetitive development tasks, while keeping architecture, code quality, and technical decisions under my control. What you can expect when working with me • Clean, maintainable, and scalable code • Independent problem-solving and technical ownership • Clear and reliable communication • Strong attention to UI details and user experience • Early identification of technical risks and potential issues • Efficient development supported by modern AI tools • Smooth collaboration with designers, backend developers, product managers, and other developers I care about more than simply making a feature work. A good solution should fit naturally into the existing codebase, remain easy to maintain, and continue to scale as the product grows. I’m available for long-term collaborations, ongoing Flutter development, part-time engagements, and project-based work. If you’re looking for a Flutter developer who can take ownership, solve problems independently, and deliver clean, production-ready work, feel free to send me a message. I’d be happy to hear more about your project and see how I can help.
