Freelance Software Developer

About

I’m a freelance software developer turning ideas into store-ready and web-ready products.

For 3+ years I’ve been building end-to-end mobile applications with Flutter and Native Android (Kotlin/Java), applying Clean Architecture, MVVM and modern state management (Bloc, GetX, MobX, Provider). On the web side I build fast, scalable products and backend services with Next.js and Node.js.

My priorities are the right technology choices, clean and sustainable architecture, and solutions that genuinely serve business goals. I’ve delivered multiple apps live on the App Store and Google Play, and on freelance projects I own the whole process from idea to launch.

I develop and maintain native Android and cross-platform Flutter applications, taking features from requirement analysis through release. I built a SIP-based VoIP client for macOS with the Linphone SDK — incoming/outgoing call management, conference calls, codec prioritisation, Auto Gain Control (AGC) and noise reduction behind a SwiftUI interface. I apply Clean Architecture and MVVM to keep modules testable and collaborate with backend and design teams on REST API contracts and UI specs.

I built Qoolline, a Flutter-based e-SIM store and management app released on the App Store and Google Play, using MobX for state management and Dio for API integration. I integrated Stripe for secure payments and OneSignal for real-time push and social sign-in. For Demirören Media I built a modular on-duty pharmacy finder, shipped as a module inside the CNN Türk super app (Google Maps SDK, Retrofit2, Coroutines, LiveData, Dagger Hilt, Room).
