I am building Android applications using Java and Kotlin. with MVC, MVP, MVVM, MVI, and Retrofit to deal with Restful API and JSON. Use jetPack compose to make your UI more user-friendly. I Use SQLite &Room to handle data caching. handle push notifications, real-time database, and cloud store by using Firebase. I Use RXJava, Coroutine, and Flow to handle threading. using Hilt, Kodein, and Koin to increase the performance of Apps.
