Development and refinement of an Android application
570 USD Hello!
Improve the application for payment automation. Stack: kotlin, android, graphql
I will write a detailed technical specification with screenshots in private messages
Stack
- Kotlin
- Android
- Graphql
Please attach Git repositories to your responses; we do not consider applications without them. Open a part of the code where we can assess your level - architecture and code cleanliness
The application already exists; it needs debugging and polling added.

I work with Kotlin Android, I have experience integrating GraphQL Apollo Apollo3 in commercial projects.
I am ready to refine the application, analyze the current architecture, and carefully make changes without disrupting the existing logic.
Below, I leave a code snippet that shows my approach to the MVVM architecture, clean logic, working with coroutines, and GraphQL.
I am ready to move to private messages, look at your full technical specification with screenshots, and discuss the details.

Creating user-friendly, intuitive interfaces and finding unexpected solutions is my specialty. Do you have a task for refining an Android application using GraphQL? That is exactly my profile!
While working on complex systems, I have gained the skill to quickly adapt to existing code and solve software debugging tasks. I am ready to apply these skills to your application, adding the necessary polling — your goal will become my task.
I will show snippets of code from my previous projects on GitHub to demonstrate my approach to architecture and code.

I have extensive experience in developing applications for iOS and Android (over 10 years).
I can work with someone else's code, debug, and fix logical errors.
I also have experience with GraphQL.
I can provide part of the code in a private message to demonstrate my level.
I work on an hourly payment basis.
Did you mean pooling?
Thank you for your attention!

class PaymentViewModel(
private val repository: PaymentRepository
) : ViewModel() {
private val _state = MutableStateFlow<PaymentState>(PaymentState.Idle)
val state: StateFlow<PaymentState> = _state
fun sendPayment(amount: Double, methodId: String) {
viewModelScope.launch {
_state.value = PaymentState.Loading
try {
val result = repository.sendPayment(amount, methodId)
_state.value = PaymentState.Success(result)
} catch (e: Exception) {
_state.value = PaymentState.Error(e.message ?: "Unknown error")
}
}
}
}
и еще пример для GraphQ репозитория
class PaymentRepository(private val apollo: ApolloClient) {
suspend fun sendPayment(amount: Double, methodId: String): String {
val response = apollo.mutation(
SendPaymentMutation(amount, methodId)
).execute()
if (response.hasErrors()) {
throw IllegalStateException(response.errors?.first()?.message)
}
return response.data?.sendPayment ?: "OK"
}
}

Добрый день. Подскажите, пожалуйста — требуется ли полная переработка архитектуры приложения или доработка текущего функционала (например, добавление поллинга)? Это важный момент для точной оценки объёма.
