Summary
👤
Senior🎓
Top SchoolKemal Çetinkaya is a Senior Android Developer based in Cologne with 13+ years focused on mobile engineering and over 17 years in software overall, specializing in banking and medical IoT apps. He architects Android apps using MVVM, Clean Architecture and Dagger2, drives CI/CD and mobile DevOps (Azure, Jenkins, Fastlane), and has a strong track record of improving performance and test coverage across large-scale apps. At Akbank he helped maintain a 10M+ download banking app and later migrated legacy MVP projects to modern MVVM and Jetpack Compose at Appsfactory, integrating BLE medical devices like glucose and ECG monitors. Equally comfortable full‑stacking with React/Node and building developer tooling (device farm portals, Slack bots), he mentors juniors and consistently embeds unit and UI tests into delivery pipelines. Notably, his background spans low-level Android work from SDK 2.3 days to modern Kotlin ecosystems, giving him rare depth across Android’s evolution.
