Hi, I’m
Azad Kızıltaş
Freelance Software Developer
I build end-to-end applications for mobile and web.
With Flutter, Next.js and Node.js I turn your ideas into scalable, store-ready and web-ready products.
About
I’m a mobile & software developer with 3+ years of experience building user-focused, clean-architecture apps with Flutter and Native Android (Kotlin/Java). I’ve delivered multiple apps live on the App Store and Google Play, and integrated a module into a nationally distributed super app. My priorities are the right technology choices, sustainable code and solutions aligned with business goals.

Tech I Work With
Experience
Mobile Developer (Android / Flutter) · Betik Bilişim
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.
Mobile Developer (Android / Flutter) · PXL Digital Solution
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).
