Vipul S.
Senior Flutter & Mobile App Developer | Android & iOS | 7+ Years
Senior Flutter & Mobile App Developer with 7+ years of experience building, maintaining, and improving production-ready Android and iOS applications. I specialize in Flutter development with a strong focus on clean architecture, performance optimization, and long-term stability. I have extensive experience working with existing codebases, helping clients fix bugs, refactor unstable code, improve performance, and safely add new features without impacting live users. I’m also comfortable building Flutter applications from scratch and taking them through the complete release process. My core strengths include: • Flutter app development for Android & iOS • Bug fixing, refactoring, and performance optimization • Firebase integration (Auth, Firestore, FCM, Cloud Functions) • REST API & real-time feature integration • Push notifications & in-app purchases • App Store & Play Store publishing and updates I’ve delivered and supported apps across e-commerce, healthcare, finance, social platforms, taxi booking, fitness, and productivity tools, always focusing on reliability and smooth user experience. I value clear communication, clean code, and dependable delivery, and I’m comfortable working in Agile environments with remote teams. If you’re looking for a Flutter developer who can quickly understand your app, fix issues safely, or take long-term ownership, I’d be happy to discuss your project.
