Native app modernisation.

Tradera is Sweden’s largest circular marketplace. I joined its Android team during a period of app modernisation and ongoing product development.

As a senior software engineer, I modernised the Android app while supporting regular feature work and releases.

I moved the legacy Java codebase to Kotlin and Jetpack Compose and applied MVVM, Coroutines and Flow. I established automated testing, weekly releases and app publishing workflows so the team could keep shipping during the migration.
