  • Integrate native device features (camera, push notifications, location, storage, biometrics).
  • Connect apps to backend APIs, handle offline state, caching, and synchronization.
  • Implement monetization features where required (in-app purchases, ads, subscriptions).
  • Review, debug, optimize, and refactor mobile application code to improve correctness, performance, battery efficiency, and maintainability.
  • Debug platform-specific issues and prepare builds for distribution (TestFlight, Play Console).

  • Bachelor's or Master's Degree in Computer Science, Engineering, Information Technology, or related technical fields is a plus.

Academic and/or Professional Experience

We are looking for specialists who can confidently work with native or cross-platform frameworks, integrate device APIs and backend services, and build production-ready mobile applications. Strong attention to detail, performance awareness, and the ability to work independently are essential.
Technical Skills (Essential)
  • Hands-on experience with at least one of: React Native, Flutter, Swift/SwiftUI (iOS), or Kotlin/Jetpack Compose (Android).
  • Solid understanding of mobile UI patterns, navigation, state management, and platform guidelines.
  • Experience integrating REST APIs, handling async data, and managing local storage.
  • Familiarity with native device APIs (notifications, camera, location, storage, biometrics).
  • Experience with mobile build tools, code signing, and submission to App Store / Google Play.
  • Experience implementing in-app purchases, ads, or subscriptions is a plus.
  • Familiarity with backend services such as Firebase, Supabase, or similar is a plus.

Additional requirements
  • Strong attention to detail and commitment to performance, stability, and platform polish.
  • Self-directed work ethic with the ability to ship complete mobile features independently.
  • Portfolio of shipped mobile apps (required, with App Store / Google Play links preferred).
  • English proficiency: Upper-intermediate (B2) or above (required)

Project time expectations
