Experience

Mova

Android Developer · Istanbul

Aug 2026 — Present

Developing Maya, a native Android application for a school-trip platform, using Kotlin and Jetpack Compose. Enables parents to discover trips, manage wishlists, complete contract and passport requirements, and pay via credit card, installments, or bank transfer.
Applied Clean Architecture with a unidirectional dependency flow (UI → ViewModel → UseCase → Repository → Data Source), ensuring separation of concerns and testable domain logic.
Implemented MVI-inspired state management using immutable UiState objects exposed via StateFlow and sealed classes for user actions, keeping composables focused on UI rendering.
Building the native Android version from the ground up with Hilt, Room, Retrofit, Coroutines, Flow, DataStore, Coil, and Firebase Crashlytics and Remote Config.
Implemented core user flows, including trip discovery, trip details, cart management, checkout and payments, favourites, and price alerts.
Improved application reliability through unit and Compose UI testing, accessibility enhancements, process-death state restoration, and localized error handling.
Contributed to release management and code reviews.

Projects

Movira LIVE · ANDROID & iOS

Cross-Platform Movie & TV Discovery App

Designed, developed, and published a movie and TV show discovery application on both Google Play Store and Apple App Store from a single Kotlin Multiplatform codebase, with shared business logic and UI built in Compose Multiplatform.
Structured the app with Clean Architecture (domain, data, presentation) and MVI with StateFlow-driven unidirectional UI state; dependency injection with Koin, networking with Ktor, image loading with Coil 3, and offline caching with SQLDelight.
Built AI-powered “For You” recommendations using OpenAI GPT-4o-mini, served through a serverless backend of Cloudflare Workers (TypeScript) that also proxies TMDB with a language-aware edge cache and a Durable Object based rate limiter, keeping all API keys out of the client.
Integrated Firebase Authentication (Google Sign-In), Cloud Firestore, Storage, App Check, and Cloud Messaging; monitored stability with Sentry and Firebase Crashlytics.
Localized the app into 8 languages and monetized it with Google AdMob and UMP-based consent management.
