About

I am Çağrı Döşeyen. I have been developing Android applications with Kotlin and Java since 2022. Alongside building new projects with current tooling, I have experience maintaining and extending long-running production apps. On iOS, I work with SwiftUI.

In the teams I have worked with, I have maintained production apps, developed new features and managed the Google Play release process. Maintainable architecture, testable code and stable releases are areas I consider important.

I also develop and publish my own apps, from the initial idea to the store release.
