Kotlin Multiplatform Expert | Android & iOS | SpringBoot | Mobile App

Building a high-performance mobile application requires more than just writing code—it requires a robust architecture that can grow with your business. Whether you are launching a greenfield project or need to refactor a legacy codebase, I specialize in delivering production-ready mobile solutions that are clean, testable, and easy to maintain. My core expertise lies in Kotlin Multiplatform (KMP). I bridge the gap between Android and iOS, helping teams reduce development overhead and codebase maintenance by sharing logic without sacrificing native performance. Why work with me? Architectural Rigor: I don’t just implement features; I build systems. My work is anchored in Clean Architecture, MVI, and MVVM patterns, ensuring your app is built to scale. Proven Delivery: I have a track record of shipping complex applications—from ride-hailing platforms like Feres to secure, high-traffic messaging apps—handling everything from UI implementation to intricate backend integration. Modern Workflow: I leverage AI-assisted engineering to accelerate development and debugging, applying rigorous human engineering judgment to ensure your product remains rock-solid and secure. My Technical Stack: Frameworks: KMP, Compose Multiplatform, Jetpack Compose. Architecture: Clean Architecture, MVI, MVVM, Multi-module Gradle. Backend/Integration: Ktor, Retrofit, REST APIs, DTO mapping, Error Handling. Database/Storage: Room, DataStore, Firebase, FCM/APNs. Advanced Features: Maps, Location Tracking, Chat, Media (ExoPlayer/CameraX), QR Scanning. Recent Success: I recently led the KMP frontend refresh for the Feres suite (Ride-hailing, Driver, and Delivery apps). This project required complex platform-specific implementations (expect/actual), seamless push notifications, and high-performance UI implementation using Compose. If you are looking for an engineer who communicates clearly, respects deadlines, and treats your codebase with the care it deserves, let’s discuss how I can help bring your project to the next level.
