Develop tasks relevant to your expertise: cross-platform applications using TypeScript, JavaScript, or Dart; iOS applications using Swift; or Android applications using Kotlin
For each task, define the problem, build a reproducible environment, and write deterministic verifiers that accept correct solutions across different valid implementations while rejecting incorrect, incomplete, or hard-coded approaches
Provide a reference solution showing how the task can be solved

Cross-platform: TypeScript or JavaScript with React Native, or Dart with Flutter
iOS: Swift with SwiftUI or UIKit
Android: Kotlin with Jetpack Compose or the Android View system
Deep understanding of mobile application architecture, state management, asynchronous programming, and application lifecycle
Proven ability to debug complex mobile applications, resolve bugs, and deliver effective performance improvements

Compensation Structure

Compensation is output-based; experts are paid per task that meets the project specifications. The time required to complete work may vary depending on the expert s experience and workflow. Minimum weekly submission requirements apply and will be communicated during onboarding.
