🌟8+ Years Experience | 50+ Projects | 20,000+ Hours | $900K+ Earned | Upwork Top Performer | Flutter Developer | Mobile App Developer
I’m a Flutter developer, mobile app developer, full stack developer, and web developer with 8+ years of experience building, fixing, and scaling mobile products for startups and growing companies. My work spans mobile app development, web development, and backend-connected product work, with a strong focus on clean architecture, smooth user experience, reliable delivery, and scalable app development.
I’ve worked across Flutter, Flutter Dart, Flutter Firebase, React, React Native, Xamarin developer projects, Xamarin Forms, Xamarin.Forms, .NET MAUI developer builds, Swift developer work, SwiftUI, iOS, Android, iOS developer tasks, iOS Swift, Android developer tasks, Android Kotlin, Kotlin, native app developer projects, AI app development, MVP development, API integration, and cross platform mobile app architecture. I also support teams that need a practical full stack developer who can connect mobile apps with APIs, dashboards, cloud services, and web systems without slowing the project down. That mix of mobile app development and web development lets me work across the full product, not just one part of it.
On Upwork, I’ve delivered 50+ projects, earned $800K+, and worked 20,000+ hours helping clients launch MVPs, modernize old apps, fix unstable codebases, and move products into production. That experience taught me how to balance speed with quality, especially when a project needs to ship quickly but still be stable enough for real users. It also taught me how to work with different teams, different product stages, and different technical constraints without losing momentum.
For new products, I help with MVP development from concept to launch. For existing products, I step in to improve architecture, refactor weak areas, and make the app easier to maintain and scale. If you’re building a cross platform mobile app, I can help choose the right direction between Flutter, React Native, .NET MAUI, Xamarin migration, or native app development depending on the product goals, timeline, and long-term plan. I focus on making those choices practical, not trendy, so the app can grow without becoming harder to manage.
I’m also a strong fit for AI app development projects where the product needs more than a basic interface. That might mean smart workflows, automated actions, backend logic, or API integration that connects the app to real business systems. In those projects, I pay close attention to stability, data flow, security, and the user experience, because a useful feature only matters if it works reliably in production.
💡 Areas I specialize in
- SaaS and startup MVP development - from idea to production-ready MVP.
- Cross platform mobile app architecture - Flutter, React Native, and .NET MAUI.
- App modernization and legacy migration - Xamarin to .NET MAUI, Flutter, or React Native.
- API integration and backend connectivity - for apps that need stable data flow and real-time features.
- AI app development and product automation - for teams that want smarter app experiences.
- Continuous delivery, refactoring, and codebase optimization - to keep existing products moving forward.
- Mobile app development for iOS and Android - with a focus on stability, performance, and usability.
- Full stack developer support - when mobile work needs web, API, or backend coordination.
- Native app developer support - when the project needs platform-specific quality and performance.
- React Native developer support - for teams already working in JavaScript-based mobile stacks.
- Swift developer and iOS developer support - for polished Apple ecosystem apps.
- Android developer support with Kotlin - for strong native Android performance.
- Flutter developer support - for fast cross platform mobile app delivery.
- Xamarin developer support - for legacy apps that need modernization or migration.
- .NET MAUI developer support - for teams moving toward a modern Microsoft stack.
- Cross platform mobile app delivery - when one codebase needs to support iOS and Android efficiently.
I’m a good fit when you need a mobile developer who can think beyond screens and help shape the full product. Whether the goal is a fresh MVP, a native app for iOS or native Android or a cross platform mobile app that can grow over time, I focus on code quality, maintainability, and practical results. I also make sure the work stays aligned with product goals, so the app is not just built well, but built in a way that supports growth and future updates.
🚀 If you need a Flutter developer, React Native developer, Xamarin developer, .NET MAUI developer, Swift developer, iOS developer, Android developer, Kotlin developer, mobile app developer, web developer, MVP development specialist, API integration expert, or full stack developer who can bring structure to a complex build and get it shipped, I’m ready to help.

I’m a 𝐌𝐨𝐛𝐢𝐥𝐞 𝐀𝐩𝐩 𝐃𝐞𝐯𝐞𝐥𝐨𝐩𝐞𝐫 specializing in 𝐑𝐞𝐚𝐜𝐭 𝐍𝐚𝐭𝐢𝐯𝐞 I build and improve iOS and Android apps for startups, founders, agencies, and businesses that need clean execution, reliable performance, and a product that is actually ready for users.
A good mobile app is not just a bunch of screens connected together. It is onboarding, navigation, performance, API handling, authentication, payments, push notifications, error states, App Store rules, and all the small details users notice right before they decide whether to keep the app or uninstall it with no emotional attachment.
Where I usually add value:
📲 React Native mobile app development
🧩 MVPs and startup apps
🔗 Firebase, REST APIs, and backend integrations
🧠 AI features, LLM workflows, and smart app functionality
🔐 Authentication, payments, maps, chat, and push notifications
🛠️ Bug fixing, crash fixing, and performance optimization
📦 App Store and Google Play launch support
I’ve worked with agencies and product teams that needed a dependable React Native developer who could jump into existing projects, handle overflow work, build features, fix issues, and keep things moving without needing a three-hour onboarding ceremony for every small task.
I use Cursor, Claude, and ChatGPT as part of my AI-assisted workflow to work faster, debug smarter, and reduce repetitive development time. But AI stays where it belongs as a tool, not as the person making final decisions for your production app.
My focus is simple:
✅ Clean code
✅ Smooth user experience
✅ Clear communication
✅ Scalable app structure
✅ Fewer “why is this broken?” moments
If you need a Top Rated Mobile App Developer who can build, fix, improve, or scale your React Native app, add AI-powered features, or help prepare your app for launch, I’d be happy to help you get it done properly.
