Android and Kotlin Multiplatform developer helping startups and product teams build production-ready mobile apps with KMP, Compose Multiplatform, Jetpack Compose, Ktor, Koin, and Clean Architecture. Since 2019, I’ve worked on native Android and cross-platform Kotlin apps, including ride-hailing, VPN, chat, location tracking, media, Firebase, and API-driven mobile products. I can turn Figma designs, product requirements, or existing codebases into clean, scalable app features that are easy for teams to maintain. I’m especially strong in: - Kotlin Multiplatform / Compose Multiplatform - Jetpack Compose UI from Figma - MVI / MVVM / Clean Architecture - Ktor, Retrofit, REST APIs, DTO mapping, error handling - Koin / Hilt dependency injection - Room, DataStore, Firebase, FCM/APNs - Maps, live location, chat, media, CameraX, ExoPlayer,SceneView - Multi-module Gradle architecture and convention plugins Recent work includes KMP frontend development for Feres, a ride-hailing platform, where I worked on production Android/iOS apps using Compose, Ktor, Voyager ,Koin, Room, DataStore, QR scanning, camera, location tracking, push notifications, and platform-specific expect/actual implementations. I also use AI-assisted engineering tools like Codex and Claude Code to speed up code exploration, debugging, refactoring, and repetitive implementation work. Final architecture and code decisions are always based on real engineering judgment, maintainability, and production quality. If you need someone who can understand an existing Kotlin/KMP codebase, ship features independently, and communicate clearly, I can help.
