About Me

I'm a mobile app developer based in Istanbul who believes that great apps are built at the intersection of logic and emotion. I love transforming raw ideas into clean, smooth and meaningful mobile experiences.

For me, it's not just about writing code — it's about designing interactions that feel natural, solving real problems with creativity, and crafting apps that people genuinely enjoy using. Every project is a new journey, and I bring both technical precision and creative vision to the table.

Whether it's designing intuitive interfaces, optimizing user flow, or fine-tuning the smallest details, I care deeply about building apps that don’t just work — they feel right. Outside of development, I’m passionate about music and believe that rhythm and structure shape both great songs and great software.

My Experiences

Mobile Application Developer
Xenovo Management Consulting / İstanbul, Turkey March 2025- Present
I developed a cross-platform mobile application using Kotlin with Compose Multiplatform, targeting both Android and iOS platforms. The application followed the MVVM architecture and made use of modern technologies such as Ktor for networking, Koin for dependency injection, Jetpack Compose for UI development, Coroutines and StateFlow for asynchronous and reactive programming, DataStore for local storage, and Coil for image loading.

Throughout the project, I implemented key functionalities such as PDF viewing and downloading that work seamlessly across both platforms, and file upload capabilities supporting images and PDF files with appropriate permission handling. I also developed reusable and platform-optimized UI components to maintain consistency and reduce redundancy in the codebase. Additionally, I structured navigation and managed application state effectively across different modules to ensure a smooth and maintainable architecture.
