About

After completing my Science Education degree, I transitioned into mobile application development and am currently enrolled in the Meta Android Developer Professional Certificate program, building my portfolio with real-world projects. I develop native Android apps using Kotlin and Android Studio, with experience in MVVM, Jetpack Compose, Coroutines, Flow, Room, and Ktor, and also build cross-platform apps with React Native and JavaScript/TypeScript. I value clean architecture, focus on maintainable and scalable applications with strong user experience, and bring a creative UI/UX perspective through my interest in pixel art and character design.Currently seeking entry-level mobile developer opportunities where I can contribute my skills and continue growing as a developer. Fen Bilgisi Öğretmenliği lisans eğitimimi tamamladıktan sonra mobil uygulama geliştirme alanına geçiş yaptım ve şu anda Meta Android Developer Professional Certificate programına devam ederek gerçek dünya projeleriyle portföyümü geliştiriyorum. Kotlin ve Android Studio kullanarak native Android uygulamaları geliştiriyorum; MVVM, Jetpack Compose, Coroutines, Flow, Room ve Ktor konularında deneyim sahibiyim ve ayrıca React Native ile JavaScript/TypeScript kullanarak çapraz platform uygulamalar da geliştiriyorum. Clean architecture prensiplerine önem veriyor, bakımı kolay ve ölçeklenebilir, güçlü kullanıcı deneyimine sahip uygulamalara odaklanıyorum ve pixel art ile karakter tasarımına olan ilgim sayesinde UI/UX tarafına yaratıcı bir bakış açısı katıyorum. Şu anda yeteneklerimle katkı sağlayabileceğim ve bir geliştirici olarak büyümeye devam edebileceğim junior seviye mobil geliştirici pozisyonları arıyorum.
