Are you tired of maintaining two separate codebases for Android and iOS? I help startups and businesses ship both platforms faster with a single, shared Kotlin codebase using Kotlin Multiplatform (KMP) and Compose Multiplatform (CMP). While most developers build for one platform, I specialize in the modern cross-platform stack that reduces your development cost by up to 50% — without sacrificing native performance or user experience. ──────────────────────────────────────────────────────────── 🔧 WHAT I BUILD ──────────────────────────────────────────────────────────── ✅ Cross-platform apps with shared UI using Compose Multiplatform (CMP) ✅ Shared business logic across Android & iOS with KMP ✅ Native Android apps with Jetpack Compose & Clean Architecture ✅ Migrating existing Android apps to Kotlin Multiplatform ✅ In-App Purchases, subscriptions & RevenueCat / Play Billing integration ✅ Push notifications (FCM / APNs), WebSockets & background processing ✅ REST API & WebSocket integration with Ktor ✅ Local caching with SQLDelight / Room KMP ✅ PDF generation, file handling, document upload & viewers ──────────────────────────────────────────────────────────── ⚙️ TECH STACK ──────────────────────────────────────────────────────────── Cross-Platform : Kotlin Multiplatform (KMP), Compose Multiplatform (CMP) Android : Jetpack Compose, MVVM, Clean Architecture, Coroutines, Flow iOS : SwiftUI interop, Xcode, CocoaPods / SPM integration Networking : Ktor, Retrofit, WebSockets, REST APIs Storage : SQLDelight, Room KMP, DataStore DI : Koin, Hilt CI/CD : GitHub Actions, Fastlane, App Store Connect, Play Console Other : Firebase, OneSignal, RevenueCat, Coil, Kotlin Serialization ──────────────────────────────────────────────────────────── 💼 REAL-WORLD EXPERIENCE ──────────────────────────────────────────────────────────── I've shipped production KMP apps including AI-powered tools that run identically on Android and iOS with shared networking, business logic, background task processing, PDF exports, and subscription flows. I understand both platforms deeply: Android lifecycle, iOS Info.plist entitlements, App Store review guidelines, and Google Play publishing. ──────────────────────────────────────────────────────────── ✅ WHY CLIENTS CHOOSE ME ──────────────────────────────────────────────────────────── → One developer. Both platforms. One codebase. → Senior-level experience — no hand-holding needed → Clear communication and on-time delivery → I write code you can maintain, not spaghetti you'll regret If you want a developer who truly understands Kotlin Multiplatform and Compose Multiplatform not just someone who Googled it — let's talk. Send me a message describing your project and I'll respond within a few hours.

🌟 Top-Rated Plus by Upwork 🌟 I'm a Senior Developer with a wealth of experience in Android & iOS development, both frontend and backend. I do native development (Swift, Kotlin) and frameworks such as React Native and Flutter.

I have 5 years of experience as a software developer, covering mobile, multi-platform, and web development. I’ve worked both in freelance and corporate Agile/Scrum environments with cross-functional roles across design, QA, and product. I’m equally comfortable joining existing teams as a freelancer or working solo to build and ship end-to-end solutions. I focus on building scalable, user-centered, and maintainable products — always aligning with business goals while writing clean, testable code.

🌟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 developer, API integration expert or full stack developer who can bring structure to a complex build and get it shipped - message or invite me - I’m ready to help!
