  • Jetpack Compose for UI
  • Hilt for dependency injection
  • Timber for logging
  • Retrofit for networking
  • GitHub Actions for CI

I have used MVVM pattern and decided on using single module since this is a very small app and I wanted to focus more on UI. Nevertheless, I have maintained package structure that would allow separation for multi module project. I am willing to discuss my choices on tech interview.


App is based on Marvel API therefore require providing API KEY.

Add API_KEY="<YOUR_KEY>" to local.properties file in the root of the project.

Github Actions loads mine API key from secrets to be able to build and run checks.
