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.

I build production-ready Flutter and React Native apps for iOS and Android, and I specialize in one thing most developers avoid , cleaning up and scaling AI-generated codebases built with Lovable, Bolt, Cursor, or Claude Code.
If your vibe-coded MVP works but needs a real developer to fix the bugs, restructure the code, and get it live on the App Store and Play Store , this is exactly what I do.
What I regularly build:
Secure authentication & role-based access
Subscriptions, in-app purchases & payments
Real-time features (chat, live updates, WebSockets)
API-driven and data-intensive applications
Clean, scalable architecture for long-term growth
AI-generated MVP cleanup & production scaling
I understand how AI tools generate code, where they cut corners, and how to turn an unstable MVP into a shippable product without rewriting everything from scratch.
What clients can expect:
Clean, maintainable code
Honest timelines & daily/weekly progress updates
Clear communication in plain English
Smooth App Store & Play Store delivery
Tech stack: Flutter, React Native, Firebase, Node.js, Laravel, REST APIs, databases, subscriptions, payments, and real-time systems.
